Prepare for L.E.K.’s case interviews and identify which digital assessment evidence fits your office and role.

The following formats come from the older Fishbowl account. Use them only as optional familiarization if your invitation indicates a comparable games assessment.
Category practice
The account describes choosing numbers that satisfy an operation and target. General HireVue practice is a category match, not confirmation of the current L.E.K. exercise.

The same account describes comparing highlighted patterns with earlier patterns and connecting pipe pieces. It gives no official game names. The examples are historical and should not determine your entire preparation plan.
Our L.E.K. Consulting question set supports preparation for the video interview stages described in this guide. Each question is labeled by its evidence: officially published, candidate-reported, or a practice question written for this company or role. Use the timed mock to practice answering aloud.
Preparation for L.E.K. should leave substantial time for explaining business decisions. A digital screen and a case conversation measure different things in different settings: familiarity with short online tasks cannot replace a clear, testable approach to a client problem.
Start with the office and entry level on your application. Keep notes about the source and date of any candidate account so that an older process does not become an assumed requirement for your own application.
L.E.K. accepts applications from university and business-school candidates as well as people moving from other careers. Its application page describes multiple interview rounds and both quantitative and strategic cases, with the mix varying by region and level.

The recruitment privacy notice dated January 2020 names Applied as an online assessment provider for certain London vacancies. This is a limited provider disclosure; it neither identifies a universal London test nor establishes a games requirement. Treat that older disclosure as historical context and follow the platform named in your current invitation.
A 2026 discussion describes a digital invitation after a Lateral Associate application, with another contributor reporting a similar Life Sciences Specialist invitation. Neither supplies enough verified detail to establish the test’s vendor or content.
L.E.K. explains that case interviews reveal how candidates organize information and experience to reach and defend a business conclusion. The result and the reasoning both matter to preparation.

The official application page says candidates may apply to only one of L.E.K.’s global offices per year. Choose carefully rather than submitting parallel applications based on different process rumors.

An older Fishbowl discussion, shown as six years old when reviewed, describes a friend’s HireVue invitation followed by three games. The office is not identified, and the account is secondhand. It supports a historical report, not a current firm-wide requirement.
The reviewed official recruiting pages do not publish a shared score threshold, game count, invitation window or retake interval. Ask the recruiting contact about an unclear instruction before beginning.
L.E.K.’s global guidance establishes the core structure while leaving office-specific details open.

Recruiting seasons vary by region. A case-interview schedule, digital-test expiry and office application deadline are separate dates.
| Cycle | Application dates | Likely assessment window | Evidence |
|---|---|---|---|
| Office-specific recruiting cycle | Use the advertised office and role deadline | Use the invitation’s expiry and timer | Official source L.E.K.’s application page directs candidates to regional opportunities rather than a single global calendar. The reviewed guidance does not establish a firm-wide decision turnaround. Source: L.E.K. Apply |
The exercises below are original practice suggestions. Use them to build habits you can apply to an unfamiliar case rather than memorizing a supposedly guaranteed question.
Estimate annual demand for a product in a city. Define the population, eligible customers, purchase frequency and average spend. Explain why each assumption is reasonable, then test which assumption drives the result most strongly.
Practice a short profitability problem with revenue, price, volume and costs. After calculating, give a decision in one sentence and identify the biggest uncertainty. A number is useful only when its implication for the business is clear.
Ask a practice partner to introduce a contradictory fact halfway through a case. State which part of your earlier argument it weakens, update the analysis and preserve conclusions that still hold. Avoid defending an initial answer simply because it was yours.
Choose examples involving a disagreement, a difficult deadline and learning an unfamiliar subject. Explain your personal contribution, the tradeoff you faced and a measurable outcome. Add a reflection on what you would repeat or change.
Read a published L.E.K. case or insight related to the office’s work. Identify the business decision that interests you and connect it to skills you have practiced. Use this as a starting point for an informed conversation, not a memorized compliment.
The evidence does not establish that. There is an older games account, a January 2020 London-specific Applied disclosure and more recent unspecified digital-assessment reports. Your invitation identifies the relevant route.
Not necessarily. Read the task description and equipment requirements. The term digital assessment alone does not specify a recorded-video format.
Prepare around the advertised role and the case guidance supplied to you. A useful general foundation is careful arithmetic, explicit assumptions and a clear explanation of what the result means.
Practice live cases with spoken reasoning, concise recommendations and follow-up questions. Reserve separate preparation time for any digital format explicitly named in your invitation.
