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

1. Why do you want to work as a business consultant, and what do you think the day-to-day work involves?

Why they ask: They want to confirm you understand the realities of consulting, including the travel, pace and client focus.

2. How would you structure an ambiguous client problem so that you can solve it systematically?

Why they ask: Structured problem solving is the core technical skill of consulting.

3. A client's profits have fallen by twenty per cent over two years. How would you approach working out why?

Why they ask: Case-style questions are standard in UK consulting interviews and test structure and commercial instinct.

4. Which strategic frameworks do you find useful, and when would you avoid using them?

Why they ask: They want to know you apply frameworks with judgement and not mechanically.

5. How would you estimate the size of a market when you have very little data? Take the UK market for electric vehicle charging points as an example.

Why they ask: Market sizing tests structured estimation and numerical comfort.

6. Which tools do you use for data analysis and presenting your findings, and how do you make sure your analysis is robust?

Why they ask: They need to know you can handle data competently and produce reliable output.

7. Tell me about a time you made a recommendation to a client and it was adopted. What made the difference?

Why they ask: They want evidence that you can turn analysis into action, not just reports.

8. You present your recommendation and the client's director rejects it, saying it will not work in their organisation. What do you do?

Why they ask: Consultants regularly face resistance, and they want to see resilience and diplomacy.

A sample answer to question 1

Why do you want to work as a business consultant, and what do you think the day-to-day work involves?

I am drawn to consulting because it combines analytical problem solving with real influence on how organisations operate, and the variety keeps me learning quickly. From what I have seen and from speaking with consultants, the day-to-day work involves scoping a client's problem, gathering and analysing data, interviewing stakeholders, building a structured view of the issues and then developing recommendations, often in a team and against tight deadlines. Much of the time goes into building models and slides, running workshops and presenting to clients, and managing relationships as much as producing analysis. Projects are usually a few weeks to several months, with time at the client site and sometimes travel. I accept that hours can be demanding, but I find that satisfying when the output genuinely helps a client make a decision. My previous roles in operations gave me the sector knowledge to contribute from the start.

Common mistake to avoid: Romanticising prestige; Ignoring travel and hours
