How L.E.K. Consulting uses custom assessments to identify consulting talent

When L.E.K. opens an associate intake, strong applicants arrive in volume. The ones who go on to succeed are not those with the most polished CV, but those who can reason through a quantitative problem and explain a clear answer.

The best resume is rarely the best consultant

A resume screen cannot tell those candidates apart. Two applicants with similar credentials can differ enormously in the one thing the job depends on: how they actually reason through an unfamiliar problem.

And interviewing everyone at scale is not feasible, so a large, competitive pool has to be narrowed on something more reliable than a CV. L.E.K. needed to test the exact thinking the job requires, objectively, and apply it the same way to every applicant.

An all-custom battery built around consulting reasoning

L.E.K. built its screening entirely on its own assessments, eleven custom tests and not a single off-the-shelf one, deliberately mirroring the reasoning a consultant uses daily. Each assessment measures a specific consulting competency, creating a structured evaluation framework instead of relying on generic aptitude tests.

• Numerical and logical reasoning. The quantitative core of the associate role, tested directly.
• Data interpretation. Whether a candidate can read data and draw the right conclusion, not just compute an answer.
• Qualitative comprehension and communication. Across 15,000+ responses, including video, L.E.K. sees how a candidate argues a case, the actual output of the role.

A competitive intake decided on thinking

L.E.K. now selects associates on demonstrated reasoning rather than the strength of a CV. Because every applicant sits the same all-custom battery, recruiters compare candidates on how they actually think, giving an objective, defensible basis for a high-stakes selection.

The custom assessment focuses on the reasoning and analytical skills required for L.E.K.'s consulting roles.

That authoring choice matters: a generic aptitude test would measure general cleverness, but L.E.K.'s battery measures the specific way its associates have to reason, so a strong score means readiness for the actual work.

A consistent hiring standard for every associate candidate

The screen is built to be demanding, designed to separate genuine consulting reasoning from a strong resume, and applied identically across the intake. For a firm where reasoning is the product, that consistency is what makes a competitive hiring decision that the firm can stand behind.
