Eight Management Consultant interview questions, and what the interviewer is thinking

1. Here's a short case: a UK supermarket chain is considering launching a same-day grocery delivery service. How would you help them decide whether to do it?

Why they ask: Case questions are the standard way consultancies test structured thinking, commercial sense and communication in real time.

2. What does a management consultant at your level actually do day to day on an engagement?

Why they ask: They want to check you have a realistic picture of the job beyond the glamour.

3. What does MECE mean, and how do you use an issue tree to break down a problem?

Why they ask: They want to see the structured problem-solving discipline that underpins consulting work.

4. How do you prepare for and run an interview with a client stakeholder to gather information?

Why they ask: They want to see that you can extract insight from people efficiently and build trust.

5. How do you quality-check your analysis before it goes in front of a client?

Why they ask: They want assurance that your work is reliable, because one wrong number can destroy client trust.

6. Tell me about a time you had to get up to speed quickly on an industry you didn't know.

Why they ask: Consultants switch sectors often, so they want to see how fast and effectively you learn.

7. What is a spans and layers analysis, and how would you carry one out?

Why they ask: They want to see practical knowledge of a common organisation design and cost tool.

8. Your engagement manager is away and the client's CFO asks you directly for an early view on savings that you're not yet confident in. What would you do?

Why they ask: They want to see good judgement about client communication and protecting the firm's credibility.

A sample answer to question 1

Here's a short case: a UK supermarket chain is considering launching a same-day grocery delivery service. How would you help them decide whether to do it?

To begin, I'd want to clarify the objective first: is it about growing revenue, defending share against rapid-delivery players, or using spare store capacity? Assuming it's profitable growth, I'd structure the problem into four areas. First, demand: how many customers want same-day delivery, how much they'd pay, and how much would be incremental rather than shifting from existing click-and-collect or next-day orders. Second, economics: average basket size, delivery fee, picking cost per order, last-mile cost per drop, and the likely contribution per order. Third, operational feasibility: whether stores can pick from the shop floor without hurting in-store shoppers, or whether dark stores are needed, plus driver availability. Fourth, competition and strategic fit, given that several grocers and aggregators like Deliveroo and Uber Eats already partner in this space, which suggests a partnership might beat building it in-house. I'd then form a hypothesis, for example that a partnership pilot in dense urban areas is the best route, and test it with a few quick calculations.

Common mistake to avoid: Diving into numbers without a structure; Ignoring cannibalisation of existing channels
