Inquiry about L.E.K online test - London office

Question

I have been invited to complete the L.E.K. online assessment for the London office this October and would like to ask a few questions about its format.

Could you please share some information regarding the structure of the test, such as the number and type of questions, the overall difficulty level, and whether the numerical reasoning section is similar in style to GMAT-type questions?

Thank you

Hi there,

I see Evelina has already provided a great answer below.

A couple of extra points:

The format keeps on changing. So feel free to also address this question to the recruiter to get the last view on the current format of the test.
Even though it changes, it's not by much. Meaning, you can use older versions of the test, or tests from other firms (e.g., Kearney, Roland Berger) as guidance for the LEK one
Below is a guide that contains the most common formulas and terms that show up in these tests:

Good luck!

Hi there,

The L.E.K. London online assessment is usually a numerical reasoning and business logic test designed to simulate real consulting-style problem-solving. Here’s what to expect:

Structure: Around 20–25 questions in 35–40 minutes (varies slightly by year). Most are multiple-choice and based on charts, tables, and graphs — similar to case data.
Content: Primarily numerical reasoning (percentages, ratios, growth rates, interpreting data), with a few logical or data interpretation questions.
Difficulty: Comparable to GMAT Integrated Reasoning or SHL numerical tests, but more business-focused — you’ll often calculate KPIs or compare performance metrics rather than just pure math.
Tips:
- Practise data-heavy problems under time pressure.
- Get comfortable with mental math and quick estimation.
- Use resources like GMAT Quant, BCG/LEK-style test prep, or assessment practice sites with business-oriented numerical questions.

Happy to help you prep for cases – feel free to reach out.

Best,
Evelina
