Key Takeaways

 

The LEK digital assessment is a timed online screen, and the right preparation depends on which of three formats you are sent.

 

  • LEK uses the digital assessment to screen applicants before inviting them to case interviews

 

  • The format varies between a short game-based test, an SHL-style aptitude test, and a longer case-style data test

 

  • Most versions run between 10 and 75 minutes and reward speed plus accuracy over deep strategy

 

  • The single best first step is to email your recruiter and confirm exactly which test you will take

 

  • Strong mental math and fast chart reading matter more than memorizing case frameworks

 

  • Passing leads to two interview rounds built around candidate-led cases and a written case

 

What Is the LEK Digital Assessment?

 

The LEK digital assessment is an online test that LEK Consulting sends candidates early in recruiting to screen for analytical ability before interviews. Depending on your region and role, it takes the form of a short game-based test, an SHL-style numerical reasoning test, or a longer case-style data exercise lasting up to 75 minutes.

 

LEK Consulting was founded in 1983 by three former Bain partners, and it screens hard for the analytical instincts that define its candidate-led case style. The digital assessment is the first filter in that process. It lets recruiters rank a large applicant pool before committing interviewer time, as the firm explains on its careers pages.

 

Treat the test as the gate between your application and the LEK case interview. Clear it, and you move into live interviews. Miss it, and your application usually stops there.

 

Why Does LEK Use a Digital Assessment?

 

LEK uses a digital assessment for the same reasons most top firms now run consulting pre-screening tests: it widens the applicant pool, removes some human bias, and saves interviewer hours. In my years interviewing at Bain, I watched screening shift from resume-only filtering toward standardized tests, and LEK has followed that same path.

 

There are four reasons LEK leans on the assessment:

 

  • Efficiency: recruiters can rank thousands of applicants without scheduling a single call

 

  • Wider access: strong candidates from non-target schools get a fair shot to prove their ability

 

  • Less bias: a standardized test reduces some of the subjectivity in early screening

 

  • Signal: results flag who has the raw quantitative speed the associate job demands

 

What Formats Does the LEK Digital Assessment Use?

 

The LEK digital assessment shows up in three main formats, and candidates report seeing different ones depending on office, role, and recruiting cycle. The table below summarizes how they compare so you know what to expect once your invitation arrives.

 

Format

Length

Questions

What it tests

Game-based assessment

~10 minutes

Several mini-games

Mental math, memory, logic, composure

SHL-style aptitude test

45 to 60 minutes

20 to 35 per section

Numerical and verbal reasoning under time

Case-style data test

60 to 75 minutes

20 to 30

Chart reading, business judgment, recommendations

 

Format 1: The game-based assessment

 

The shortest version is a set of mini-games that takes around 10 minutes, often delivered through HireVue. The games start simple and grow more complex, and you do not need to be a gamer to do well.

 

Candidates typically report three game types: a mental math game where you pick two numbers that solve a problem, a pattern memory game where you recall highlighted shapes, and a logic puzzle such as connecting pipes inside a fixed grid. The format closely resembles the BCG Pymetrics test, so practice for one transfers well to the other.

 

These games measure your composure and your ability to think clearly under pressure. There are no behavioral or essay questions in this version.

 

Format 2: The SHL-style aptitude test

 

The aptitude version is a timed, multiple-choice test of numerical and verbal reasoning, usually delivered through a platform like SHL. It runs roughly 45 to 60 minutes and asks you to interpret tables, charts, and short passages quickly.

 

Numerical questions cover percentages, ratios, growth rates, and reading data from exhibits. Verbal questions ask you to judge whether a statement is true, false, or impossible to determine from a passage. A calculator is sometimes permitted, so confirm the rules before you start.

 

Format 3: The case-style data test

 

The longest version is a case-style exercise of 20 to 30 data-heavy questions that can take 60 to 75 minutes. Charts and exhibits sit at the center, and you must independently spot what matters without an interviewer prompting you.

 

Some versions add short written responses or ask you to select the most practical recommendation. Answers are judged on logic and business sense, not just arithmetic, so a clean calculation paired with a weak conclusion still costs you.

 

Which Version of the LEK Digital Assessment Will You Get?

 

You cannot always predict which format you will receive, so the safest move is to ask your recruiter directly. A few signals point you in the right direction before that reply lands.

 

  • Region: UK and European offices more often use SHL-style aptitude tests

 

  • Role: undergraduate and associate roles tend to see the shorter game-based or aptitude version

 

  • Invite wording: an email naming a games platform points to mini-games, while a long completion window points to a case-style test

 

  • Cycle: formats change year to year, so last season's experience is only a rough guide

 

If you have already taken the McKinsey Solve, the case-style version will feel familiar in its emphasis on reading data fast and making a call. The game-based version, by contrast, feels closer to a set of brain teasers than a business case.

 

How Long Is the LEK Digital Assessment?

 

The LEK digital assessment takes anywhere from about 10 minutes to roughly 75 minutes, depending on the format you are assigned. The game-based version is the quickest at around 10 minutes, the SHL-style aptitude test runs 45 to 60 minutes, and the case-style data test stretches to 60 to 75 minutes.

 

LEK usually gives you a window of several days to complete the test. The test itself is timed once you begin, so do not start until you are ready to give it your full focus.

 

How Is the LEK Digital Assessment Scored?

 

Scoring depends on the format. Game-based versions rank you by how closely your profile matches the traits of successful consultants, so there is no single right answer. Aptitude and case-style versions score you on accuracy and speed, then compare your result against a benchmark to decide who advances.

 

The practical takeaway is the same across formats: answer as many questions correctly as you can within the time limit. Guessing late is usually better than leaving questions blank on the multiple-choice versions.

 

How Do You Prepare for the LEK Digital Assessment?

 

The best preparation targets speed and accuracy under pressure rather than fancy frameworks. Having coached hundreds of candidates through online screens, I have found that disciplined math and fast data reading carry far more weight than memorized case structures. Work through the six tips below.

 

Tip #1: Confirm the exact format with your recruiter

 

Before you prepare for anything, email your recruiter and ask which test you will take and how long it lasts. This single step tells you whether to drill mini-games, aptitude questions, or case-style exhibits, and it saves you from preparing for the wrong thing.

 

Tip #2: Sharpen your mental math

 

Fast, accurate arithmetic is the backbone of every format. Practice percentages, ratios, growth rates, and multiplication until they feel automatic, the same skills you will need for case interview math later.

 

Here is an illustrative example of the speed you want: if revenue grows from $400 million to $500 million, you should see a 25% increase in a couple of seconds. Build that reflex and the timed sections stop feeling rushed.

 

Tip #3: Drill chart and exhibit interpretation

 

The aptitude and case-style versions live on charts, so train yourself to read one in seconds. Pull up company investor slides and practice answering a single question from each exhibit: what is the trend, the biggest driver, and the number that matters.

 

For example, given a chart showing a segment growing at 30% a year while the rest of the business is flat, you should immediately flag that segment as the story. That instinct is exactly what the test rewards.

 

Tip #4: Practice under a timer without a calculator

 

Many versions limit or ban calculators, and all of them are timed. Run your practice with a stopwatch and only the math you can do by hand or on paper, so test day feels like a rehearsal rather than a surprise.

 

Tip #5: Run full practice tests in the right format

 

Once you know your format, complete a few full-length practice runs. Sample SHL-style numerical reasoning tests build pacing for the aptitude version, while self-guided case questions with no interviewer prompts mirror the case-style test.

 

If you have not yet built a base of case skills, learning how to prepare for a consulting interview first will make the case-style questions far easier to read.

 

Tip #6: Set up your tech and environment

 

Take the test on a charged, plugged-in device with a stable connection in a quiet room. Read every instruction before you start, since one wrong assumption early can cost you the screen.

 

What Happens After You Pass the LEK Digital Assessment?

 

Passing the LEK digital assessment moves you into live interviews, usually run across two rounds. The first round is two back-to-back cases of about 30 minutes each, led by associates and consultants, with a few behavioral questions mixed in.

 

LEK cases lean heavily on market sizing and quantitative reasoning, and the firm is known for healthcare and life sciences work in many markets. If you want to learn case interviews quickly, my case interview course walks you through proven strategies in as little as 7 days.

 

The final round usually adds two to three more cases with managers and partners, plus a written case interview that runs about 60 minutes and asks you to analyze a slide deck and present findings. Expect harder math and tighter time than the first round.

 

Behavioral questions run through both rounds of the final round as well, with prompts like why LEK and tell me about a time you led a team. My fit interview course covers how to answer 98% of these questions in a few hours.

 

Treat the LEK digital assessment as the warm-up rather than the main event. Confirm your format, drill timed math and chart reading, and you will give yourself the best shot at reaching the case rounds where offers are won.

 

Frequently Asked Questions

 

What is the LEK digital assessment?

 

The LEK digital assessment is an online test that LEK Consulting sends candidates early in recruiting to screen analytical ability before interviews. Depending on your region and role, it appears as a short game-based test, an SHL-style numerical reasoning test, or a longer case-style data exercise. Passing it earns you an invitation to the LEK case interview rounds.

 

How long is the LEK digital assessment?

 

It depends on the format. The game-based version takes about 10 minutes, the SHL-style aptitude version runs roughly 45 to 60 minutes, and the case-style data version can take 60 to 75 minutes with 20 to 30 questions. Candidates are usually given a window of several days to complete it.

 

Is the LEK digital assessment hard?

 

The difficulty comes from time pressure, not advanced material. The math sits at a high school level and the logic is intuitive, but you must work quickly and accurately. Most candidates who fail run out of time or rush in without reading the instructions, so pacing and composure matter more than raw intelligence.

 

What is the LEK SHL test?

 

The LEK SHL test is a psychometric aptitude assessment that measures numerical reasoning, verbal reasoning, and problem solving under timed, multiple-choice conditions. It is one of the formats LEK may use to screen candidates before the case interview. It rewards fast, accurate data interpretation rather than memorized frameworks.

 

Can you practice for the LEK digital assessment?

 

Yes. While the game-based version cannot be studied like a normal test, you can prepare by drilling timed mental math, practicing chart and table interpretation, and running sample SHL-style numerical reasoning tests. For case-style versions, practicing self-guided case questions where no interviewer prompts you is the most useful preparation.

 

What happens after you pass the LEK digital assessment?

 

Successful candidates are invited to interviews, usually across two rounds. The first round is two back-to-back cases of about 30 minutes each with associates and consultants, plus a few behavioral questions. The final round adds two to three more cases with managers and partners and a written case interview that runs about 60 minutes.
