Hi there!

Congrats!

Basically, for the personal fit part, prepare the following questions:

• Tell me about yourself
• Walk me through your CV
• Why consulting / Why switching from your current employer
• Why LEK
• Why this role
• What are your strengths / What are your areas of development

For the market sizing exercise - yes, this will be different from the case. They might ask you something like what is the number of phone minute calls each day in Spain. You then need to come up with an approach and assumptions in order to reach that number.

For the case - as far as I understand, you are applying for a generalist position, and in this situation you can expect any type of case from any industry. Sharing with you a few examples below with detailed interviewer notes:

Hi there,

1) Does anyone what the market sizing and cases are like? 

Based on the feedback of the candidates I coached, most market sizing questions asked by LEK are demand-based (eg “How many XYZ are sold in the US?”).

2) Are the market sizing and the cases two different tasks or will the market sizing be part of case? 

From the feedback of my candidates, both situations could occur at LEK, but I saw a higher number of standalone market sizing.

3) What types of cases do they usually use?

The common types I saw are opportunity assessment (i.e., choose between 2 or more alternatives), operations, growth strategy, market entry and profitability.

If you need help please feel free to PM me, I know 40+ real questions asked at LEK.

Best,

Francesco

Market Sizing:

1. Market sizing is typically a separate task from the case portion of the interview.
2. You will be given a specific market or industry scenario and asked to estimate the size or market share of a particular segment or product.
3. The interviewer will be assessing your ability to think logically, use relevant data, and make reasonable assumptions to arrive at a well-reasoned estimate.
4. It's important to communicate your thought process clearly and structure your approach using a framework, such as the top-down or bottom-up method.

Case Interview:

1. The case portion of the interview will assess your problem-solving and analytical skills.
2. You will be presented with a business problem or scenario and asked to provide recommendations or solutions.
3. The cases can cover a wide range of topics, including market entry, growth strategy, profitability analysis, pricing, and mergers and acquisitions.
4. It's crucial to listen carefully to the case prompt, ask clarifying questions, and structure your approach using a framework tailored to the specific case.

Remember, each interviewer may have their own style and preferences, so it's important to adapt and be flexible in your approach

Hi there,

First of all, congratulations on the invitation from L.E.K.!

I would be happy to share my thoughts on your situation:

• First of all, while I do not know in detail about whether market size estimations will be integrated into a larger case studies or not, I would highly advise you to be prepared for anything.
• Moreover, as for the types of cases, L.E.K. usually focuses on growth strategies, market entry, and commercial due diligence cases. Still, they could test on other types as well.

You can find more on this topic here: How to succeed in the final interview round.
