Consulting prescreening tests are online assessments that firms like McKinsey, BCG, Bain, and Deloitte use to filter candidates before interviews. According to McKinsey's recruiting data, roughly 80% of candidates who take these tests are eliminated, making the prescreening test the single largest cutoff point in consulting recruiting.

 

This guide covers every prescreening test used by major consulting firms, what skills they measure, how difficult they are, and exactly how to prepare. Having coached hundreds of candidates through these assessments at Bain, I will walk you through what actually matters for each test.

 

But first, a quick heads up:

 

McKinsey, BCG, Bain, and other top firms accept less than 1% of applicants every year. If you want to triple your chances of landing interviews and 8x your chances of passing them, watch my free 40-minute training.

 

What Is a Consulting Prescreening Test?

 

A consulting prescreening test is an online assessment that evaluates your cognitive abilities, problem solving skills, and personality traits before you reach the interview stage. These tests sit between your application submission and your first round of live interviews.

 

Firms use prescreening tests because they receive thousands of applications for a limited number of interview slots. According to a 2025 McKinsey careers report, top consulting firms receive over 200 applications per open position at most offices. Running every applicant through live case interviews would be impossible, so the prescreening test acts as an automated first filter.

 

The good news is that prescreening tests are predictable. Each firm uses a specific test format, and the skills being evaluated are well known. With the right preparation, you can significantly improve your chances of passing. In my experience, candidates who spend even 5 to 7 days preparing for their prescreening test score meaningfully higher than those who go in cold.

 

Prescreening tests differ from case interviews in an important way. Case interviews test your ability to solve a business problem in a live conversation. Prescreening tests evaluate your raw cognitive abilities and behavioral traits through structured exercises, games, or multiple choice questions. You do not need any business knowledge or consulting experience to perform well on most prescreening tests.

 

Which Consulting Firms Use Prescreening Tests?

 

Nearly every major consulting firm now uses some form of prescreening test. The specific test varies by firm, office, and sometimes by candidate type. Based on candidate reports from 2025 and 2026, here is a comparison of the prescreening tests used across the consulting industry.

 

Firm	Test Name	Format	Duration	Key Skills
McKinsey	McKinsey Solve	Gamified simulations	65 min	Critical thinking, data analysis, systems thinking
BCG	Pymetrics, CCA, Casey Chatbot	Games, behavioral quiz, chatbot case	25 to 45 min	Cognitive traits, logic, case solving
Bain	SOVA, TestGorilla, HireVue	Aptitude test or video	40 to 75 min	Numerical, verbal, logical reasoning
Deloitte	Online Immersive Assessment	Situational scenarios	30 to 45 min	Situational judgment, problem solving
EY	EY Online Assessment	Numerical and verbal test	40 to 60 min	Numerical reasoning, verbal reasoning
PwC	PwC Psychometric Assessment	Aptitude and situational test	30 to 50 min	Cognitive ability, personality
KPMG	KPMG Aptitude Test	Situational judgment test	30 to 45 min	Situational judgment, numerical reasoning
Oliver Wyman	Oliver Wyman Online Assessment	Numerical and logical test	45 to 60 min	Numerical reasoning, logical reasoning
Kearney	Kearney Recruitment Test	Multiple choice aptitude	30 to 45 min	Quantitative skills, problem solving

 

One important detail: the test you receive often depends on your specific office location, not just the firm. For example, Bain's London office typically uses SOVA, while several US offices use TestGorilla. Always check with your recruiter or read the invitation email carefully to confirm which test you will take.

 

What Does Each Firm's Prescreening Test Look Like?

 

While all consulting prescreening tests aim to measure similar underlying skills, each firm uses a different format. Understanding what you will face is the first step toward performing well. Below is a breakdown of every major test.

 

What Is the McKinsey Solve?

 

The McKinsey Solve is a gamified online assessment consisting of two ecology themed simulations: Redrock Study and Sea Wolf. As of 2026, the test takes approximately 65 minutes of active game time. McKinsey retired the older Ecosystem Building game in mid 2025.

 

In Redrock Study, you analyze data about wildlife populations, perform calculations, and complete a case style report. In Sea Wolf, you select microbes to treat polluted ocean sites based on their biological characteristics. Neither game requires business knowledge or gaming experience.

 

A critical detail most candidates miss: the Solve does not just score your final answers. According to McKinsey's official test guidelines, it tracks every click, scroll, and decision you make. Your problem solving process counts just as much as getting the right answer. Based on Glassdoor reports from 2025 and 2026, approximately 30% to 40% of candidates who take the Solve advance to interviews.

 

What Are BCG's Prescreening Tests?

 

BCG uses multiple prescreening tests depending on the office and stage of the process. As of 2026, most candidates will encounter two or three of the following assessments.

 

• BCG Consulting Career Assessment: A 30 to 35 minute test with behavioral questions and math and logic problems. BCG began rolling this out in 2025 as the first screening step for many offices. You typically have 24 hours to complete it after receiving the invitation. For a full breakdown, see our BCG Consulting Career Assessment guide.

 

• BCG Pymetrics Test: A set of 12 neuroscience based mini games that measure 91 cognitive traits, including attention, risk tolerance, emotional intelligence, and decision making. Each game takes 1 to 3 minutes. There are no right or wrong answers. BCG uses AI to compare your behavioral patterns against those of successful consultants. See our BCG Pymetrics test guide for details on every game.

 

• BCG Casey Chatbot: A 45 minute chatbot driven case interview with 20+ questions. You interact with a chatbot named Casey that presents a business case, asks quantitative and qualitative questions, and then records your final recommendation via video. This is the primary first round screening tool at most BCG offices as of early 2026. For preparation tips, check out our BCG online case and chatbot guide.

 

What Is the Bain SOVA and TestGorilla?

 

Bain uses different online assessments depending on the office. As of 2026, here are the three main formats candidates encounter.

 

• Bain SOVA: A five section blended assessment covering numerical, verbal, and logical reasoning, plus personality and situational judgment questions. It takes 60 to 75 minutes. There is no visible timer, but the system tracks your speed. Faster correct answers score higher. Based on candidate reports, the estimated passing threshold is around 70% to 75% on the reasoning sections. Used primarily in European and Middle Eastern offices. For detailed preparation strategies, see our Bain SOVA test guide.

 

• Bain TestGorilla: A 30 to 40 minute multiple choice assessment covering numerical reasoning, business judgment, leadership, and situational decision making. Bain introduced TestGorilla in 2024 and it is now used in several US and European offices. You must have your webcam on during the test. See our Bain TestGorilla guide for a full walkthrough.

 

• Bain HireVue: A video based assessment used in some Southeast Asian and Australian offices. This combines recorded video answers with automated scoring of your communication and reasoning.

 

The best way to find out which test you will take is to check with your Bain recruiter or read the email you receive after submitting your application.

 

What Is the Deloitte Online Assessment?

 

Deloitte uses an immersive online assessment that places you in realistic work scenarios. Rather than traditional multiple choice aptitude questions, the Deloitte assessment asks how you would respond to situations you might face as a consultant. You receive a personalized feedback report after completing the test.

 

The assessment typically takes 30 to 45 minutes. It evaluates situational judgment, problem solving ability, and cultural fit. According to Deloitte's recruiting website, the test is designed to measure your natural approach to work rather than textbook knowledge. For a complete overview of Deloitte's interview process, see our Deloitte case interview guide.

 

What Tests Do Other Consulting Firms Use?

 

Beyond MBB and Deloitte, most major consulting firms use some form of aptitude test or situational judgment assessment. The specific test varies by firm and often changes from year to year.

 

• EY: Uses an online assessment with numerical and verbal reasoning components. Some EY offices also include a one way video interview as part of the screening process.

 

• PwC: Uses a psychometric assessment that combines cognitive ability testing with personality evaluation. The test is typically 30 to 50 minutes.

 

• KPMG: Uses an aptitude and situational judgment test. Candidates report that the KPMG test emphasizes how you would handle real consulting scenarios more than raw math ability.

 

• Oliver Wyman: Uses an online assessment focused on numerical and logical reasoning. The test is known for being more quantitatively demanding than some other firms' assessments.

 

• Kearney: Uses a recruitment test with quantitative and problem solving questions. The format is similar to a traditional aptitude test.

 

What Skills Do Consulting Prescreening Tests Measure?

 

Despite their different formats, consulting prescreening tests evaluate a core set of overlapping skills. Understanding these skills helps you focus your preparation on what actually matters. Based on published test descriptions and candidate feedback across all major firms, here are the five skill categories that appear most frequently.

 

• Numerical reasoning: Your ability to interpret data, perform calculations, and draw conclusions from numbers. This appears on nearly every consulting prescreening test. According to a 2024 analysis of consulting aptitude tests, around 80% of test takers find the numerical section the most time pressured.

 

• Verbal reasoning: Your ability to understand, analyze, and evaluate written information. You will typically read a passage and determine whether statements are true, false, or cannot be determined based on the information given.

 

• Logical and abstract reasoning: Your ability to identify patterns, complete sequences, and apply rules to new situations. This includes tasks like matrix puzzles, figure series, and rule based sorting exercises.

 

• Situational judgment: Your ability to choose the most appropriate response to a workplace scenario. These questions assess leadership, teamwork, and decision making under realistic conditions.

 

• Behavioral and personality traits: Your natural cognitive and emotional tendencies, such as risk tolerance, attention to detail, and emotional intelligence. These are measured through game based assessments like BCG Pymetrics and are typically scored as non directional, meaning there are no objectively right or wrong answers.

 

Skill	McKinsey	BCG	Bain	Deloitte
Numerical reasoning	Yes (embedded in games)	Yes (CCA, Casey)	Yes (SOVA, TestGorilla)	Limited
Verbal reasoning	Limited	Limited	Yes (SOVA)	Limited
Logical reasoning	Yes (core focus)	Yes (CCA)	Yes (SOVA, TestGorilla)	Yes
Situational judgment	No	Yes (CCA)	Yes (TestGorilla)	Yes (core focus)
Behavioral traits	Yes (process scoring)	Yes (Pymetrics)	Yes (SOVA personality)	Yes

 

The practical takeaway: if you build strong numerical reasoning, logical thinking, and data interpretation skills, you will be well prepared for the prescreening test at almost any consulting firm.

 

What Are the Pass Rates for Consulting Prescreening Tests?

 

Pass rates vary significantly by firm and test. Here is what we know based on publicly available data, Glassdoor reports, and candidate feedback from 2025 and 2026.

 

• McKinsey Solve: Approximately 20% to 40% of test takers advance to interviews. The wide range reflects differences across offices and candidate pools. The older Problem Solving Test had a pass rate of about 30%, and the Solve appears to filter candidates at a similar or higher rate.

 

• BCG Pymetrics: Pass rates are not publicly disclosed. Because Pymetrics scores are non directional (based on behavioral fit rather than right or wrong answers), the pass rate depends on how closely your cognitive profile matches BCG's internal benchmarks.

 

• Bain SOVA: Candidates report that the estimated passing threshold is around 70% to 75% on the reasoning sections. The personality section does not have a pass or fail score but contributes to overall evaluation.

 

• Big 4 tests (Deloitte, EY, PwC, KPMG): Pass rates tend to be higher than MBB because these firms hire more candidates relative to their applicant pools. However, exact figures are not publicly reported.

 

The key insight is that consulting prescreening tests are a real bottleneck. At MBB firms, more candidates are eliminated at the prescreening stage than at any other single point in the hiring process. Taking these tests seriously is not optional.

 

How Should You Prepare for a Consulting Prescreening Test?

 

The right preparation strategy depends on which test you are taking. However, in my experience coaching hundreds of candidates through consulting assessments, there are universal principles that apply across all prescreening tests.

 

How Much Time Do You Need to Prepare?

 

Most candidates need 5 to 7 days of focused preparation to feel confident on their prescreening test. That assumes 1 to 2 hours of practice per day. If you have strong quantitative skills from a math, engineering, or finance background, you may need less time. If mental math or data interpretation does not come naturally, plan for closer to 10 days.

 

According to a survey of successful MBB candidates on Glassdoor, candidates who spent at least 5 hours specifically preparing for their prescreening test were roughly 2x more likely to advance than those who did no specific preparation.

 

What Is the Best Day-by-Day Preparation Plan?

 

Here is a 7 day preparation plan that works across McKinsey, BCG, and Bain prescreening tests. Adjust the emphasis based on your specific test format.

 

• Days 1 to 2: Learn the format. Read our detailed guide for your specific test. Understand how many sections there are, what question types appear, and how scoring works. Take one untimed practice run to see where you stand.

 

• Days 3 to 5: Practice by section. Focus on your weakest areas first. If numerical reasoning is your biggest challenge, spend extra time on data interpretation and mental math drills. Practice under timed conditions to build speed and accuracy.

 

• Days 6 to 7: Take 2 to 3 full length timed practice tests. Simulate real test conditions: no interruptions, no extra resources (unless your test allows a calculator), and strict time limits. Review every mistake and understand why you got it wrong.

 

Preparing for prescreening tests is just the first step. If you pass, you will face case interviews next. If you want to learn case interviews quickly, my case interview course walks you through proven strategies in as little as 7 days, saving you hundreds of hours of trial and error.

 

What Are the Best Free and Paid Practice Resources?

 

The best starting point is always the official practice materials provided by the firm itself. After that, third party simulations can give you additional reps.

 

• McKinsey: McKinsey provides a practice Solve environment on their careers website. Use it before your real test. The practice version does not count toward your score.

 

• BCG: BCG offers sample Pymetrics games through the Pymetrics platform. For the Casey chatbot, BCG provides four official sample questions on their interview preparation website.

 

• Bain: Bain does not provide official practice tests, but the numerical, verbal, and logical reasoning questions on the SOVA and TestGorilla are similar in format to standard aptitude tests available on platforms like JobTestPrep and SHL.

 

• General aptitude practice: Free practice resources from SHL, Korn Ferry, and other test providers can help you build speed on numerical and verbal reasoning questions that apply across multiple firms' tests.

 

What Are the Most Common Mistakes on Consulting Prescreening Tests?

 

Having debriefed hundreds of candidates after their prescreening tests, I see the same mistakes come up again and again. Avoiding these will put you ahead of most applicants.

 

• Not checking which test your office uses. Different offices within the same firm often use different tests. Preparing for the SOVA when your office uses TestGorilla wastes time and leaves you underprepared. Always confirm your specific test before you start studying.

 

• Ignoring process scoring. On the McKinsey Solve, your problem solving process is tracked and scored alongside your final answers. Rushing to the answer without showing logical steps can hurt you even if you get the answer right. Take a deliberate, structured approach.

 

• Trying to game behavioral tests. On assessments like BCG Pymetrics, some candidates try to guess what the "right" personality looks like and fake their responses. The algorithms are designed to detect inconsistent behavior. In my experience, candidates who play naturally outperform those who try to manipulate the results.

 

• Poor time management. Many prescreening tests have tight time limits. Spending too long on one question means running out of time for easier ones later. If a question is taking more than 90 seconds on an aptitude test, flag it and move on.

 

• Skipping preparation entirely. Some candidates assume they can rely on raw intelligence. According to research by SHL, candidates who practice aptitude tests score 20% to 30% higher on average than those who take the same test cold. A few hours of practice makes a real difference.

 

Frequently Asked Questions

 

Can You Retake a Consulting Prescreening Test?

 

In most cases, no. If you fail a prescreening test, you cannot retake it for the same application cycle. McKinsey's Solve results are valid for 12 months, so if you reapply in a future cycle, you may need to take it again. Bain and BCG follow similar policies. This is why preparation matters. You typically get one shot per recruiting cycle.

 

Do All Consulting Firms Require a Prescreening Test?

 

Not all, but most do. Among MBB firms, McKinsey requires the Solve for the majority of candidates. BCG uses the Pymetrics, CCA, or Casey chatbot for most applicants. Bain's requirements vary by office. Some boutique strategy firms skip prescreening tests entirely and go straight to case interviews. Check with your target firm's recruiting team to confirm.

 

Can You Use a Calculator on Consulting Prescreening Tests?

 

It depends on the test. The McKinsey Solve explicitly allows a physical calculator, pen, and paper. The Bain SOVA and TestGorilla generally do not allow calculators. BCG's Pymetrics games do not involve calculations that need a calculator. Always read the instructions in your invitation email to know what tools are permitted for your specific test.

 

How Long Are Consulting Prescreening Test Results Valid?

 

McKinsey's Solve results are valid for 12 months. If you took the Solve for one McKinsey application, you will not need to retake it for another McKinsey application within the same 12 month window. BCG Pymetrics results typically last for the duration of your application cycle. Bain's policy varies by office and test format. Contact your recruiter if you are unsure whether your previous results still apply.

 

What Happens After You Pass a Consulting Prescreening Test?

 

After passing your prescreening test, you will be invited to the next stage of the interview process. At most firms, this means first round case interviews. McKinsey's first round typically includes two back to back interviews, each with a case and personal experience questions. BCG and Bain follow a similar two interview first round format. The prescreening test is your ticket to these live interviews, so treat it as a critical milestone in your consulting recruiting journey.
