LEK Consulting Interview Questions

The assessment process at LEK Consulting is:

• Online application
• First round interviews
• Second round interviews

First Round Interviews

The first round of interview is two 45-minute interviews with separate interviewers. Both interviews include case study questions. Other questions are a mix of analytical brain teaser questions and company/culture fit questions. The analytical questions will vary from basic mental arithmetic to more complex case studies with maths.

Previous candidates have been asked:

• Tell me about your degree / PhD
• Why have you chosen consulting as a career?
• Why have you applied to LEK?
• Where else have you applied?
• What motivates you?
• Why do you want to leave academia?
• Why did you study 'your subject'?
• Why did you do a PhD?

You may also be asked brain teaser questions/analytical such as:

• How many piano tuners are there in the UK right now?
• What is the weight of a fully-loaded Jumbo Jet at take-off?
• What’s the benefit of the Channel Tunnel Rail link?

Case Study Questions

Previous candidates have also been asked the following case study questions:

• What is wrong with the train system in the UK? ..How would you fix the problems?
• A brick manufacturer wants to supply nationwide, how does he decide how many factories to build, apart from the main factory based in Leicester?
• What would a pharmaceutical company take into consideration if it was thinking of

entering the generics market?

• Estimate the profit and loss account of Liverpool F.C.

For all case study questions your interviewer will be looking for you to describe the structure of the costs and revenues involved. They are looking to see how you work things out and if you go about things in a sensible manner. The accuracy of your figures is less important, although it is possible that after the initial cast study discussion your interviewer may give you specific numbers and expect you to do some basic, but more accurate calculations.

Company Fit

At least one interview will be with a third year associate, who will be interviewing you to check if you are someone they could work with.

Company fit is important at LEK. If your interviewers do not think you will fit in to the company for some reason, they will not take your application any further, no matter how good you are on paper.

Second Round Interviews

If you are successful at the first stage interviews, you will be invited to a second stage round of interviews which follow exactly the same process as the first round. The questions asked will however, be much harder than the first round, and your interviewers will either be partners or high level managers.
