LEK Consulting online test guide: numerical reasoning and case prep
LEK Consulting candidates should prepare for fast numerical reasoning, online case-style tasks and later case interviews. This page is narrower than the main LEK Consulting assessments guide: it focuses on the exact test format candidates search for when they receive an assessment invite. For broader stages, compare the employer assessment hub.
Source note: forge checks these company-test pages against official provider guidance from SHL, Aon, and HireVue, then treats employer-provider links as provisional. Use the guide to choose the right transferable drill, but let your invitation email override any public report on provider, timing or section order. If the invite is vague, prepare the named skill first, then add one adjacent format so you are not surprised by a mixed battery.

LEK Consulting assessment route map
Use the table below to turn the wording in your invitation into a practice route. The employer name is useful context, but the test label is what should decide your first drill.
| Invite wording | What it usually means | Best first practice |
|---|---|---|
| SHL-style numerical, digital/case assessment and case interviews | Closest reported provider or format signal for this page. | numerical reasoning and case assessment |
| Market share and growth calculations | The first question family most candidates should make familiar. | Practise SHL numerical free on forge |
| Profitability and margin comparisons | A second likely skill area, especially in mixed online batteries. | Prepare consulting assessments |
| Recorded interview, video interview or final stage | The assessment has moved from speeded testing into evidence and motivation. | Prepare concise examples for why LEK Consulting, why this role and one tested strength. |
Question types to practise first
Do not practise every psychometric topic equally. For this page, start with the question types below because they are closest to the reported LEK Consulting format.
- Market share and growth calculations
- Profitability and margin comparisons
- Chart interpretation
- Case recommendation logic
Do not stop at reading the format. Build speed with a timed drill. Practise SHL numerical free on forge
If your invite includes a second format, practise that separately. Prepare consulting assessments
Representative sample question
The exact test may use a different scenario, but the underlying arithmetic and reading traps are usually familiar: percentages, ratios, base selection, inference from a passage, or judgement under constraints.
Percentage change = (100 - 80) / 80 x 100 = 25%.
The trap is the base. Dividing by the new figure gives 20%, which is a common distractor in provider-style numerical tests. Always divide the change by the original value.
How to use this guide with your invite
Before you start practising, compare the words in your invitation with the provider signal above. If it names SHL, AON, HireVue, Cappfinity, Pymetrics or another platform, follow that provider route first. If it only names the skill, such as numerical reasoning or situational judgement, practise the closest transferable format and keep one session for the adjacent skill most likely to appear next. That keeps your prep specific without betting everything on a provider claim that may be outdated.
What forge sees candidates confuse
The common mistake is treating the company page as proof of one fixed test stack. In practice, candidates often remember the employer name and forget the assessment label in the portal. That leads to broad prep when the invite has already narrowed the work. ForLEK Consulting, start from the phrase closest to SHL-style numerical, digital/case assessment and case interviews, then check whether the task is asking for speeded reasoning, workplace judgement, game-style behaviour or recorded answers.
A useful review rule is to tag every practice miss by cause: wrong data, wrong base, over-reading, pattern guess, judgement mismatch or slow correct answer. That turns a generic numerical reasoning and case assessment session into a short list of fixes before the real assessment.
How to prepare
- Practise consulting-style maths without overusing a calculator.
- Review wrong answers by business logic and arithmetic trap.
- Pair online test prep with live case practice.
- Read the invitation email. Confirm whether LEK Consulting names SHL-style numerical, digital/case assessment and case interviews or another provider for your exact role.
- Baseline the main format. Take one timed drill for numerical reasoning and case assessment, then review every miss by trap type.
- Practise weak question types. Prioritise Market share and growth calculations, Profitability and margin comparisons, Chart interpretation before doing full mocks.
- Prepare the next stage. Build concise interview stories and rehearse any video interview answers on camera.

Note on accuracy: the test providers named in this guide reflect candidate reports and publicly available information as of 2026, and are provided for preparation guidance only. Employers do not usually publish which assessment provider they use, and these relationships change over time — LEK Consulting may switch providers, run different tests for different roles, regions or intakes, or use a provider not listed here. Nothing on this page is confirmed or endorsed by LEK Consulting or any test publisher, and it should not be relied on as a definitive statement of LEK Consulting’s current process. Always confirm the exact test and provider from your official invitation email before you prepare.
