McKinsey Solve Game: Newest Updates, Guide & Free Trial 2024

The data is over, let's continue the test?

What is the McKinsey Solve (or Problem-Solving Game)?

McKinsey Solve is a gamified, pre-interview screening test

McKinsey Solve (previously called the problem solving game, digital assessment, or an extension of the Inverse Game) is a hype-analysis created by Inverse Evaluation for McKinsey & Co.

In the process of selecting talent for McKinsey, the Solve Game implements the same problem of saving paper studies for "unsuitable" applicants, occupying the space between resume review and interview cases, to save time and resources on the expensive case line of interviews.

Solve began testing in 2017 (when it gained popularity as a digital assessment) and began large-scale implementation in 2020. Since then, Solve has been fixing cardboard analyses for task conclusions in each of McKinsey's offices.

The test is considered an Insolve for applicants who submit orders for roles in all practices, including General, Operations and Implementation, Studies and Specialists, and Digital.

Note: Because this is a gamified analysis, in this comment I will use the definitions of “game” and “test” interchangeably when referring to McKinsey Solve.

The new gamified test is supposedly crack-proof

So why did McKinsey change the test format, going from cardboard to a game? Keith McKinsey, an expert and assessment staff member at Mass McKinsey, explained in one way:

"The recruiter will only understand if the applicant has the right answer, not how he approached the question. Apart from that, surveys with different variations of answers involve a lot of strategy, preparation and success, and using them in the selection process will solidify the status quo at a time when you want to expand your circle of potential recruits.

In essence, McKinsey is trying to create a test/game that cannot be done (what can only be called the irony of fate).

But in fact it can be broken down into bite-size pieces

Thanks to the reports of hundreds of real fabric members, we were able to fairly collect information to strip McKinsey down to pieces that match all applicants to the required degree. By applying this information, you can exclude work connections from this IRGE.

In this comment we will show:

• The technical details of the test: time limit, number of tasks and mini-games, aspects of evaluation
• Analysis of each mini-game: explanation, logic found in the database, appropriate strategies
• Recommendations for passing the exam, greatly expanding your own possibilities
• As well as games McKinsey Answer Game Training

Neither Inverus nor McKinsey have published clear details about the criteria/mechanisms used in the game, so it is important to keep in mind that the data presented by the reporter in this article may not 100% reflect the components of the game.

What is the McKinsey Solve like?

McKinsey's digital assessment answer test has a time limit of 60 to 80 minutes. Candidates are asked to solve two of six mini-games. The final result, i. e. the process itself, is evaluated, and if the candidate is deemed to have similar abilities and aptitudes as McKinsey consultants, they are invited to an interview.

For deeper control over the technical elements of the game, check out McKinsey's PSG Simulation (All-in-One) package.

Sketch 1: Educational Program McKinsey Solve / McKinsey PSG

Time limit is 71 minutes

As of April 2021, the displayed time for McKinsey Solve is exactly 70 or 71 minutes, and we recommend 35 minutes for the first game (Ecosystem Building) and 35 minutes for the second game (Red Rock Research). Or 36 minutes. (Crop Protection). Time spent on the training program is not taken into account.

From the beginning of the game, the time limit varied, but it was generally in the range of 60-80 minutes. This range depends on the time of each mini-game.

Up to 2023, i. e. in the mini-game "Plant Protection": The actual time depends on the candidate's conclusion. However, since the first game is more predictable, it is recommended to act quickly to forget more time for the second game. If the situation is right, the first game will be over in about 15-20 minutes, even taking into account the time for double checking.

From summer 2023 onwards, i. e. in the mini-game "Redrock Exploration": The time for the mini-game "Creating an Ecosystem" is fixed at 35 minutes, and "Redrock Exploration" is another 35 minutes. This basically means that if you finish the first game within the time, you will not be given additional time for the second game.

Guess the mini-game challenge and mentally scroll through the team format before starting the mini-game. You can also use this time to prepare anything you need, like pen and paper, or have a light snack to refuel.

Each candidate has to solve 2 out of 6 mini-games

As of June 2023, McKinsey's Solb Test has proved six min i-games: ecosystem construction, re d-rock exploration, plant defense, disaster management, illness management, and migration management. The two major min i-games encountered by almost all applicants are ecosystem construction games and red rock exploration missions.

According to the information, the first game frame of McKin Zaesol test is 100 % "Eco System Construction". Regarding the second game frame, 80-90 % of applicants are currently "redlock research tasks", and 10 to 20 % are "plant defense" (formerly the opposite of the second game frame). In other words, McKinsey has gradually abandoned the plant defense and has shifted to the Red Rock Study Task.

The first game "Economy Construction" is similar to the theme of the building of the village, but an animal is used instead of the house, and a ecosystem with various appearance must be constructed.

Redrock Study Task uses one large study using the tool on the screen, and then solves 6 to 10 small cases with similar topics. Try McKinsey's Solve for a good cease and get the image of the game!

The remaining three games (disaster management, disease management, migration management) are considered to be another variation that McKinsey used for beta tests. In the 2023 McKinsey Solve test, these games are not given.

• In disaster management, the whole system is moved to another space to identify disasters generated in the ecosystem and minimize damage. The min i-game appeared sporadically from 2020 to 2021.
• Diseases Managemen t-identifies infections, determines the infection rules, and predicts the spread of ecosystems. The min i-game appeared sporadically from 2020 to 2021.
• Moving management is to assign an animal group from a certain point to another point to take away a smaller number of resources and animals. The min i-game appeared sporadically from 2021 to 2022.

For the latest information on this mini gam e-redrock study-, see the McKinsey Solve free trial or the simulation package for this mini game.

In the next section, we will measure the time on what the applicant is evaluated. If you are not interested in this section, you can jump directly to min i-games and strategic management from this link.

Every keystroke and mouse movement will be assessed

Each applicant is observed from both the product (final result) and the process (how and how).

The point of the product is determined by the degree of the min i-game goal.

In the first min i-game, some decisions are better than other decisions, despite the 100 % correct answer. This information is described in the report in the report. In the second min i-game, the final answer based on facts and data is the final result. There are correct and incorrect answers, but Macinsey does not know the number of correct answers/ actions.

• Mini Game 1: How many species survived?
• Mini Game 2: Did you choose the correct data point? Is the calculation and report correct? Did you choose the appropriate scheme for the data display?

On the other hand, the mall of the process is determined based on data on your actions through the entire process to solve the problem.

McKinsey consultants have two elements, "process" and "product". McKinsey has not made an official announcement of what kind of candidate to choose, but the more it looks like a competent McKinsey consultant, the more likely it will be.

Candidates are assessed on five core dimensions

The problem solving profile is shown in the following five parameters:

• Critical Thinking (critical thinking): Ability to make a reasonable judgment based on a series of facts
• Decisio n-making: Ability to select the best options
• Metabria: Ability to use strategies (hypotheses, holding records, etc.) that facilitates information and solving problems
• Status recognition: Ability to determine the relationship between various factors and predict the results of min i-games
• System thinking: Ability to understand the causal relationship including various factors and feed bucket loops (eg, the results of different orders)

A good news is that all evaluation skills are generally not sel f-evaluated. In other words, if you train a certain skill, it is likely that other skills will increase the score. This is very important, and there is no need to jump into all difficult tasks to increase the score.

In order to achieve success, all skills need to be demonstrated, but some indicators are considered more important than other indicators. From the results of this research, critical thinking, status awareness, and systematic thinking can be concluded that all successful applicants should have. < SPAN> Product points are determined by the degree of min i-game goals.

Breaking down the test – Redrock Study Task (including free practice test)

Mini-game overview & description

A good news is that all evaluation skills are generally not sel f-evaluated. In other words, if you train a certain skill, it is likely that other skills will increase the score. This is very important, and there is no need to jump into all difficult tasks to increase the score.

In order to achieve success, all skills need to be demonstrated, but some indicators are considered more important than other indicators. From the results of this research, critical thinking, status awareness, and systematic thinking can be concluded that all successful applicants should have.

• At the same time, the skills of inference and meta cognition are advanced skills that raise applicants from bad levels to great levels.
• Sketch 2: McKinsey's recruitment pipeline match rate between the median and structure (source: Invera)
• Imbellus does not completely open the collected telemetry data, so it is not literally easy to be qualified, but it is difficult once in the outline of the inference process.

Based on the results obtained from the actual applicant, remote measurement data can be divided into appropriate groups, and the main impact is in the steps from identifying the problem to the subsequent action command. I believe it will be.

Difficulty identification: Your normal thinking type

Methods theory Thinking vs. abstract thinking

Larg e-minded thinking vs. details

Breaking down the study in Part 1

Example of telemetry: Model for drawing a value, clicking, and conclusions

Quantitative tests and data integration: Ability to convert data into conclusions

Identify the relationship between data

Exclude correlation information and unrelated information

Example of telemetry data focus model, time spent on quantitative problems

• Development of hypothesis: Convert awareness to an effective guess
• Focus on specific layouts / methodology based on insights
• Example of telemetry: The stage of transition period from analysis to conclusions, and the current situation

Derivate conclusions: consistency between action and thinking

Is it a random choice or an intentional conclusion based on the analysis?

Determination to transfer the selected strategy to execution

The reaction in the increase in time constraints is vanity in contrast to peace and concentration.

Example of telemetry: The time spent on the decision between variations at the moment of acting based on the selection

Follo w-up behavior advice: Research and inference

Ability to adapt to existing strategies and try and error in front of new datasets and changing criteria

Even if you face failure and turmoil, gradually learn and reflect on it.

Remote measurement examples: Number of clicks, scroll speed, time spent on specific data blocks

The Red Rock Exploration Mission began in July 2023. Later, it was updated in March 2023, and the order was divided into two parts.

The first part of the min i-game is also very important, but it is based on a huge survey with the guidelines and a set of spare data. This part is roughly divided into three steps: research, testing, and reporting.

Phase 1 - Investigation: Your task is to review the case description, determine the target and necessary data points, and collect them in the investigation log screen.

Phase 2 - Analysis: Using the provided calculator, process the obtained data and answer three quantitative questions. These answers will be used to complete the report in Phase 3. The calculation history will be recorded.

Stage 3 - Report: Your main task is to complete a text and graph report with the results calculated in Stage 2 (you will have to choose which type of diagram you will use).

In the second part, you will have to answer 10 cases on a similar topic to the first part (for example, if in the first part there was a case specialized in selling clothes, the mini case will also be specialized in selling clothes). However, according to user reviews, this topic is purely cosmetic and will not affect the final figures.

As of July 2023, only multiple-choice questions in which you choose A, B, or C, or questions with numerical answers, were reported. There is no evidence that free-form questions were asked.

• As for the time limit, you are given a total of 35 minutes to perform both parts of the task. There is no official time limit, but to optimize your results, we recommend spending 25 minutes on the first part and 10 minutes on the second part.
• Test the game Redroc k-study with a free trial of McKinsey Solve!
• The first part of Redrock's study assignments (which we will call "studies" or "cases") is a course that focuses on checking the candidate's logical and mental skills. If you do not follow the logic carefully, the algorithm will not recognize your train of thought and will view you negatively. Here, we divide the study into four aspects.

Aspect 1: Understanding the Study

This applies to the first stage of Redrock Investments, "Investment". To really understand what to do, you must first clearly define the goal of the case. Then, the next challenge is to understand all the data presented in the case and determine which of them can be used to solve the problem.

In general, all the information you see on the screen is what you need to understand and solve the case. However, some information is less important than others. Reference information and test instructions are textual data that are usually not selectable or movable. They are only meant to provide a general overview of the case, e. g. a topic, and do not need to be collected.

Boxer, important data points are different, displayed on the cell appearance of the cell. You can drag these cells and work from inside. There are three data on the similarity of the necessary information between these data points, and you should be found for you:

• Purpose: Text data that informs the purpose that must be solved in the provided case. As a general rule, it is placed at the top of the case and the note continues immediately.
• Calculation memo: Data to inform you of what mathematical formulas are applied and what amount to choose. In many cases, it is a lon g-term text / phrase that bets between objects (such as many / few) in the case.

Hugu: Most of the data points in the case. Usually, graphs/ charts (histograms, radial diagrams), tables, and sometimes between words. In order to determine these figures on the correct line, it is necessary to collect them in a diary. Of these figures, there are only a few (10-15 %) that is really important for the case.

Sketch 3: Research data points

In general, in this rule, it is necessary to consider which formula to be applied after gathering cases of the case. Only then can collect the advantageous numbers required for calculation. Apart from this, the conclusion of the case requires only some data points.

Game Neences 2: Collection of data points

In each turn of redroc k-Test, each mobile data point can be transferred to Journal and collected. In the research diary, each collected "data point" is reflected in the appearance of a card with your own mark and description. Data from the journal can be accessed to the calculator or applied to the "answer entry" (blank under the problem).

Some data include appropriate labels according to the content, but some are not. All data marks can be manually changed. If the content is not enough in the notebook standard, we recommend that you arrange this way. Convenient marking allows you to quickly identify the correct data, leading to further speeding up tests.

After collecting data, you can record each point with the "I" button on the left side of the marking (probably "important"). When you switch to this button, you will draw all the details of the data in orange. It is recommended that you emphasize important information on the analysis line (or calculation).

In the "Research Journal", these data points can be moved up and arranged at the top. In fact, McKinsey may take into account how to create data. This will be explained later. A specific sorting method is still in setting, and as a result, it will start updating when these starts.

Game Neences 3: Data points processing for information reception

• The second line of the game offers three quantitative issues related to the goal of the game. Each problem is composed of 2-3 subchievements, and there is a column to enter an answer using a calculator. To answer these issues, you need to install the collected numerical data in the calculator in front of you and transfer the results to the suicide gap.
• This calculator has an unpretentious interface similar to a digital calculator on the phone, with the leading operator *,+,-,/. Mathematical calculations can be fully confident that ordinary calculations are usually used (as most examinees reports). However, there is no "%" button for%calculation.
• We recommend that all calculations are done on the attached calculator. In this way, we hope that the way of responding to the answer will affect the final result.

The recommended series of actions is to transfer data points from the learning diary to the calculator input screen and execute the calculation. Next, transfer the results in front of you and drop them in the blanks of the problem. Do not transfer keyboard numbers, as they may lead to aggressive type mistakes.

Here, a certain number of queries and calculations in part 1 on the second line introduces a certain number of calculations:

Basic operation (addition / subtraction / multiplication / division): Basic operations are rarely performed alone. In principle, link with difficult questions.

Conventional interest and comparison: Judge general ratio, interest, and fractions. For example, in "What is the population increase rate in 2021-2022?" It can be arranged at the top. In fact, McKinsey may take into account how to create data. This will be explained later. A specific sorting method is still in setting, and as a result, it will start updating when these starts.

Mini-game overview & description

The recommended series of actions is to transfer data points from the learning diary to the calculator input screen and execute the calculation. Next, transfer the results in front of you and drop them in the blanks of the problem. Do not transfer keyboard numbers, as they may lead to aggressive type mistakes.

Here, a certain number of queries and calculations in part 1 on the second line introduces a certain number of calculations:

Basic operation (addition / subtraction / multiplication / division): Basic operations are rarely performed alone. In principle, link with difficult questions.

Conventional interest and comparison: Judge general ratio, interest, and fractions. For example, "What is the population growth rate for 2021-2022?"

Complex interest questions: you have to calculate various ratios and percentages in succession. For example, "What will the population be at the end of 2023?" (Data provided: population at the beginning of 2022, population growth rate from 2022, projected population growth rate in 2023 compared to population growth rate in 2022).

It is important to note that the results obtained from these questions are most often required at the report stage. There is also a check screen, so be sure to collect the answers on the paper.

To get familiar with this section, you can take advantage of a free trial of McKinsey solve. Try it now!

Game aspect 4: Completing a report on the case

The "report" phase is the final part of the Red Rock study task. It consists of two parts: a resume and a data visualization.

In the CV, you fill in the blanks in the report in text form using the numbers or values ​​already given or obtained in the previous phase, and expressions such as "greater than", "less than", "equal to", etc. The blanks at this stage are most likely to be similar to the answers entered in the analysis phase.

In data visualization, you choose the right type of diagram, fill in the numbers, and create a content diagram for your report. At this stage, what makes redrock different from the old McKinsey PST is that there are no composite types of diagrams. This allows you to deal with only simple types of diagrams, such as column and circular diagrams, which greatly reduces the complexity.

Figure 5: Screenshot of questions at the report creation stage

Want to experience the simulation of this new game? You can purchase a McKinsey simulation package from McConsultingPrep.

We have released a free trial version of McKinsey Solve, so please check it out at this link before purchasing the package.

As far as we can judge, the training challenges in redrock are more similar to the problem-solving tests of its predecessors than to games. Therefore, the hints for this challenge are somewhat different from the previously popular game "Plant Protection". There is no direct formula that guarantees the best chance of survival (perhaps that's why "Plant Protection" was discontinued), but rather you have to act and think like a McKinsey consultant.

Tip 1: Apply a structured approach to data collection

McKinsey, an excellent consultant, always uses a "to p-down" approach when analyzing the problem, and recruiters often prefer candidates for this system. During the investigation, McKinsey can evaluate this feature when you collect and systematize the data.

Always collect goals first. They are the center of business, the top of the tree in question. It should always be summarized in a research diary. If it is too long, you can easily write it on paper.

The next step is to determine the formula. This type of data determines which formula should be used, and which numbers should be collected. These are called reference data. Tasks determine which relational data is required.

Finally, collect the required numbers. These are required to complete the calculation and final report. Analyze the target and related data to collect only what you need. Collecting all data randomly is that they do not have a structured thinking.

Tip 2: Market and systematization of data

As already mentioned, after collecting data in a diary, each data point is marked with a mark. Some data points already have good marks, while others are not.

McKinsey may be able to recognize good numbers, so it is recommended that you constantly change the data point brand and explanation as needed. Good labels may seem good for algorithms, and it will be easier to analyze data. There are several suggestions for points to consider to attach a good mark:

What is the time axis ("Is this data in 2020 or 2021?)

What kind of items are you talking about (such as the line, columns of spreadsheets, those represented by the graph axis).

Cracking the mini-game

Is there anything else to remember? (Footnote of chart, supplementary information, etc.).

Regarding the position of the data, it is consistent and fall. "Details of vision should be" Details ". For example, there is a target at the top of the research diary, and there is a relational data below. Macchinsey may be a proof that you are a structured person.

Tips 3: Don't go back and appeal to indecision

In this game, you can freely move from a certain stage to another stage and collect more data points. This is useful when you make a mistake or when you need a double check, but it is not recommended.

Such actions indicate that the examinees do not fully understand each section and are not confident in the task. Step 1 clearly states that McKinsey's instructions must collect all the related data before going next. Rearing back and forth can be received negatively by the algorithm.

Tip 4: Select the appropriate map type (bar / line / pyramid)

I wrote the whole guide about how to create a map like a McKinsey consultant. However, in short, it is necessary to choose the most suitable chart type to explain a specific type of data in the McKinsei style.

Access the free trial of McKinsey Solve, experience the actual simulation, and apply these hints to improve performance!

This trial has just been introduced, so it is a stage of collecting information and collecting information. Details will be updated as needed.

Test procedure, format, complexity

Part 2 has 6 to 10 cases, each with prompts, text information, and data. Each case also has a tool on the screen. The case must be solved in order. In other words, you cannot jump and answer before the next case.

All 6 to 10 cases are compatible with the same topics as part 1 learning. However, according to the test taker feedback, the topic is considered to be independent, regardless of the answer (that is, no numbers in other cases are required).

The number of words in 6 to 10 cases is 100-400 words. The only answer is basic quantity and inference skills, and no advanced mathematical skills are required. However, most examinees need to be careful as they try to solve within 10 minutes.

Type in question

The type of question in the examinee's report was almost the same as Part 1. It is divided into five types: word problem, official, linguistic inference, critical inference, and visualization. In Part 2, the frequency of these problems was mapped.

• The word problem (50 %) is a math problem that the candidates need to read and present data for answers.
• The formula (20-30 %) is a type of problem similar to an oral test, but it is only necessary for the test takers to recognize the calculation formula.
• Language thinking (7-8 %) and danger (7-8 %) are issues with countless elections, and examinees must choose "true" or "false" from 3-5 types of sentences. 。
• Visualization (10 %) is strictly required to select the correct image for the data image.
• Visualization (10 %) is strictly required to select the correct image for the data image.
• Now you can learn about these types of questions and get the answer procedure for it for free. To get a new version of Charitable Trial of McKinsey Solve from McConSULTINGPREP, follow this link!
• In the min i-game "Eco System Creation", an ecosystem with eight from 39 lists shines for you.
• (1) The ecosystem needs to create an infinite food chain.

(2) In each pair of predators and victims, the calories must be excessive (that is, the victim is more than using predators).

(3) The ecosystem must satisfy the characteristics of the territory in the selected space.

Here, we will explain the data and statistics of min i-games, and how they are related to the goal.

• Sketch 6: "Mountain" and "reef"
• Task 1: Territory ratio
• There are two scenarios that need to build an ecosystem: "Mountain" and "REEF".

Each space in the mountains contains eight appropriate data: sea level, heat, wind speed, humidity, cloud height, global pH, precipitation, and barometric pressure.

• Each leaf space contains seven appropriate data: depth, water direction, water permeability, heat, salt concentration, dissolved air, and wind speed.
• The characteristics of the territory are quite vulnerable.
• In any exterior, there is still a certain important data in the territory. If these requests are not respected, the image will disappear. These demands are not often regarded as accurate numbers, but suggests the spectrum (eg, heat: 20 to 30 ° C).
• All 39 forms are organized in three equal groups according to the characteristics of the territory. The form related to one layer certainly has a monotonous characteristics of territory.
• Assignment 2: Continuousness of food chain
• Each appearance has a certain number of natural enemies (eaten) and production (food source).
• Seeds are divided into producers (plants and corals that do not consume calories) and buyers. Buyers may be herbivorous animals (herbivorous animals), predators (animal animals), and all food animals (food and flora and fauna).

For manufacturers, the source of food is when sunlight and other natural ingredients are always when there is no prey. Some buyers are regarded as "vertex animals", that is, they have no natural predators (they can be recognized by the characteristics of "Eated by"). This includes strategic significance to building food chains.

• Assignment 3: Energy balance
• Each appearance has an indicator of "necessary calories" and "calories received". The statue is alive, which is less than the sum of the calories allocated by the form of eating (so it has enough energy to survive), and the statue is allocated. The number of calories is higher than the total calories that are allocated by appearance, what they eat (so they are not to be eaten before they become extinct).
• There are two wraps: The statue often does not absorb all of their prey and cannot be eaten by all of their predators. There are specific value standards (see the term "Duplicate of Food"), and usually, predators and victims interact only once at once.
• In a long version of the game, each picture is a group, and the groups of each group are 20 to 60. In these versions, nutritional value is displayed "for each individual", and as a result, it is necessary to calculate and manufacture everything that appears.

Breaking down the test – Plant-Defense

In the fresh version, this function has introduced a feeding function for the overall appearance as a whole, and refused to "another individual" in decisive, but in fact no expired function was introduced, substantially guarantee. Not.

Mini-game overview & description

During the game, candidates have the ability to switch space and appearance elections between min i-games. There is still time scale at the top of the screen.

According to old information, if you present your own ecosystem, you will finally receive an evaluation sheet that indicates how everything actually happens. The main indicators may be developed and consumed not only in the number of living figures.

However, recently, the report is not displayed at the end of the game. In any case, it is hard to imagine that the main base remains unchanged.

• The main difficulties in the min i-game "Eco System Construction" are relevant to priority and data processing. Most test participants say that they are overwhelmed by the amount of data and do not know how to work on tasks. However, the second problem is that McKinsey offers a tutorial and specific and detailed instructions, so it can be solved by reading the rules carefully.
• In order to solve these two problems at the same time, it is necessary to first know "the rules of food intake" (that is, how the race takes turn), and then solve these problems. You can develop a thre e-step approach.
• Figure 7: Explanation of the game interface for the construction of ecosystem
• Rules to eat food and rules to cut off food
• In McKinsey's PSG ecosystem min i-game, species are very specific and comprehensive, and they eat alternately and eat food:
• 1. The highest calorie species of the food chain first eats.

2. Eat the highest calories to eat (if the seeds to eat are breeders, you can assume that this step and step 3 to 5 are automatically avoided).

3. Seeds are "consumed" from the seeds that eat calories equal to the necessary calories, and at the same time, the amount of calorie from the species to be eaten is deducted.

4. If there are two kinds of "best prey" of the same calories, eat the amount equivalent to half of the necessary calories from each.

5. 5. If the necessary calories are not 0 (that is, satisfied), even if the seeds you eat eat all the first prey calories, you will move to the second highest prey and the above steps. Repeat. The prey that has exhausted the amount of heat has been removed from the food chain forever and is considered to be extinct.

6. When the first species are finished, repeat this cycle until all species are finished, with the second largest species, the third species with the highest heat generated. Note: In each step where the species are sorted by calorie supply, the latest values ​​(that is, the value obtained after the predator) is always used.

7. At the end of this process, all species should have a lower calorie supply and new value of calorie requirements than the original value. When the final calorie requirements are 0 and the calorie supply is larger than 0, the species survive.

Let's look at the example. Before repeating the comments, don't forget to use the standard described above, and see if it's right:

Sketch 8: Example of food chain of min i-games to build ecosystem

This food chain is determined in this way:

One producer gets mechanically necessary calories without eating anything.

The first animal that can be eaten is a rat. The rats eat the same amount of grass and mushrooms, and their calories are 2, 000 calories. The calories that are important for rats are 0, and the calories of grass and mushrooms are 3. 000, each (grass and mushrooms survive).

The second form that rats eat is the squirrel. She had to eat grass, but the grass provided only 3. 000, so the squirrels chose the nuts instead. The calories required for proteins are 0, and the calories required for nuts are 500 (nuts survive).

Cracking the mini-game

The third most eaten is a snake. Snake eats mouse, keeps important calories to zero, and 2, 000 calories out of 3, 000 calories supplied from the mouse. (Mouse survives).

The third seed that can be eaten is a snake. Snakes eat mouse, make important calories 0, and consume 2, 000 calories out of 3, 000 calories supplied from the mouse. (Mouse survives).

The fourth seeds that can be eaten are foxes. The fox absorbs squirrels, reduces important calories to 0, and deprives 2, 000 calories out of 2, 500 calories obtained by squirrels. (Squirrel survives).

The last thing to eat is a tiger. First, eat a snake, take 1, 500 calories from the snake, then take 500 calories out of 1, 200 calories from the fox, and make the important calories 0 (the snake dies and the fox survives).

Tiger cannot be eaten by other animals (Tiger survives).

Sketch 9: Conclusion of food chain in ecosystem construction min i-game

With these standards in mind, let's look at the three steps to build a food chain:

Step 1: Select space

Using electric tables and paper, we will write the characteristics of the area and the nutritional value of the products provided by min i-game manufacturers.

Looking at the data, you understand which nature of the territory is immutable in every point and which properties change. Only the characteristics of the changing territory are logical (two), and others are just "noise" created to cause excessive information.

Alternative mini-games

Calculate the amount of calories required by producers of each layer. The most calorie layer is the most common thing for building a chain immediately.

Alternative 1: Disaster Management

Step 2: Build a food chain

Check the data and enter a list of buyers that comply with exemption in your own electrical table.

• As a starting point for the food chain, choose the shortest predator.
• From top to bottom, we build a food chain like a task tree and list the highest predator food providers. Keep downwards down until you reach the "basics", which means coral and plants. Standards, food chains are required to be composed of three to four value and eight appearance.

Also, looking at the characteristics of the "eaten" of any look, the food chain can be built up from the bottom, but it cannot be reached to the highest predators. In fact, our reports indicate that this line can be the same ambulance as the descending order in actual test standards.

Alternative 2: Disease Management

Prioritize the hig h-calorie and low powers throughout the process. This can maximize the potential of excess calories in the food chain, and if the first chain does not get an important 8-look, you can forget the space for fresh additives.

When the chain is completed, proceed from the bottom to the top without reaching the necessary 8-look, find a gap (that is, unused surplus calories), and fill the gap with predators and herbivores.

To make the calculation easier, make the entire process on the electric table / paper.

Step 3: Triple test and adjustment

Alternative 3: Migration Management

Return to the beginning of the process and find out if all the exteriors in the food chain are suitable for the selected space.

Make sure that the food chain is continuous, that is, the lis t-up food information provider meets all species.

Use these power standards to receive photos in the food chain and whether they will die.

Adjust the food chain if no one of the three checks is true.

• Although McKinsey does not tolerate this test, there are still reports that it is actually used by applicants (within 10 to 20 % of communal difficulty). Therefore, this section will be left as a memo for sharing information, and will be updated if there is any change.
• The second min i-game McKinsey solves the game factory on a ste p-b y-step game in the tower defense genre. Candidates are probably long, which is necessary to use obstacles and predators to protect the plant in the center of the map from the intrusion of pests until the protection is overcome and the plants are not eradicated.

Test-taking tips for the McKinsey Solve

Sketch 10: Mini glass screen "plant protection" sketch

Tip 1: Don’t think too much about criteria and telemetry measurements

The following is a detailed explanation of gameplay:

Visually, the map is divided into a network of squares (sizes ranging from 10x10 to 12x12) interspersed with natural obstacles (called terran or terran-variant).

Tip 2: Don’t be erratic with in-game actions

The recommended time for the game is 12 minutes. 36 minutes in total during the duration.

The game is divided into three maps, each consisting of two phases: "Planning Phase" and "Acceleration Phase".

Tip 3: Always strive for a better solution (Ecosystem Building)

The Planning Phase divides 5 moves into three waves. Every 3-5 moves on the map, a new group of invaders starts moving towards the border and central base - for you it seems to create a protection project to overcome with it. The phase will not survive at the end of the 15th move until all invaders are destroyed / and your factory is not yet eradicated.

After the 15th course of the Planning Phase, the "Acceleration Phase" begins. All invaders continue to attack after the remaining Planning Phase. Your defense plan remains constant and will not be changed. Invaders will appear every day and attack until your base is annihilated.

Tip 4: Showcase fundamental skills for a McKinsey consultant (Redrock Study)

After the game ends, the number of rotations your base has expanded is used as the basis for the goods point calculation.

Nuance Game 1: Sources

• At the beginning of each wave, you can choose 5 sources and place them, divided into lawyers (Coyotes, Snakes, Falcons, etc., kill the invaders) and locations (consisting of cliffs, forests, mountains, slow down the invaders or make them jump). Each is assigned to the time of the current wave.
• After each move, the defender/territory of this course is activated and blocked. The rest can be changed by events. The only exception is the rock, which is activated immediately and then placed.
• Each lawyer has an action radius/territory, and if the invader goes to this action radius/territory, the lawyer will give him losses and reduce his population. Each lawyer has a different radius of exposure to everyone depicted in his portrait, but in general, the stronger the lawyer, the smaller its radius of influence.

Each location is effective in all sorts of ways against different types of invaders. Some block the invaders, some slow them down.

Tip 5: Prepare your hardware and Internet properly before the test

Each location and lawyer occupies 1 cell. A lawyer cannot be placed on top of an existing lawyer, and if a lawyer becomes an existing lawyer, the lawyer replaces the existing lawyer.

Defenders and territorial players form compatible pairs with each other, and each has a chance to pre-spend one space.

How to practice for the McKinsey Solve Test

Hypothesis-driven problem-solving approach

Game Nuance 2: Invaders

The intruder appears in a group of 100 to 200 at the end of the map every 3 to 5 turns, approaching your factory one step at a time. The number of stacks gradually increases.

Each of the invader's stack is linked to the route display, and the yello w-like long arrow indicates the destination. If Cliffroad is not blocked, the invader will always move this route.

Mental math and fast reading skills

Each invader faces a specific type of terrain / defense.

Practice with video games

McKinsey Solve Game's "Plant Defense" mini games are basically considered tower defense games, so use the main tactics of this genre, "building from inside" and "loss of zone". Is possible. However, this min i-game cannot be changed after a few moves, so you have to consider the effects of unexpected situations.

Let's explain each tactic in detail:

• Use different defense from the inside
• In this tactic, we build a number of defenses in a direction that is advantageous in terms of terrain from the base.
• First, find your resources near the factory. The ring inside the map is narrow, and the road tends to converge as you head to the center, so it will definitely help to maximize all resources around the factory in the first step.

In the case below, only eight resources required to protect the factory from all sides in the "inside out" layout, and 24 in the "Outsid e-in" layout. In this scenario, huge resources are located closest to the factory.

City-building games

• Think from a big perspective
• This is rather than "tactics". After 15 hands, resources cannot be replaced or assigned. Therefore, we will identify the invader's behavior pattern and adjust your strategy quickly accordingly. To find out what else is effective against an invade r-like opponent, you need some first.
• Create a model that uses resources wisely and comprehensively protects plants. On e-sided defense (that is, strong in a certain direction, but weak in other directions) will not last long, and it is the task of this min i-game. < SPAN> Invades appear in a group of 100 to 200 at the edge of the map every 3 to 5 turns, approaching your factory one step at each turn.
