Consultant Interview Questions
18 consultant interview questions on problem solving, case thinking, client handling and delivery, with what strong answers include. For both sides.
What's here
18 Consultant interview questions, grouped into 4 areas: problem solving and structured thinking, client handling and communication, delivery and teamwork and motivation and situational questions. Each one comes with why it is worth asking and what a strong answer contains, so the same question can be scored the same way by different interviewers.
- Use a short case or estimation question for every candidate so you can compare structure, not just stories.
- Interrupt gently with new information during a case to see how they adapt.
- Ask for the candidate's own contribution in every project story.

Preparing for this interview yourself? Practise it free →Consultants help clients solve problems they cannot or do not want to solve alone: diagnosing issues, analysing data, recommending changes and often helping to deliver them. The title covers strategy, management, technology and specialist consulting, but the core skills are the same: structured thinking, clear communication, client handling and getting work done under time pressure. These questions test those skills. Interviewers can use the 'what to look for' notes as a scoring guide; candidates can use them to prepare.
Problem Solving and Structured Thinking
Whether the candidate can break an ambiguous problem down and reason to an answer.
- 1
A retail client's profits have fallen for two years. How would you work out why?
Why ask it
A mini case shows structure under pressure.What to look for
Clarifying questions first, then a structure that splits profit into revenue and costs, and revenue into volume and price (by store, channel or product). Hypotheses tested with data, and a clear summary. Jumping straight to one answer is a weak sign. - 2
Estimate the number of coffee shops in a city you know well. Talk me through your thinking.
Why ask it
Estimation questions test logic and comfort with numbers.What to look for
A clear approach (population, coffee drinkers, cups per day, shop capacity), stated assumptions, sensible rounding, and a sense check at the end. The process matters more than the number. - 3
Tell me about a time you solved a problem with incomplete data.
Why ask it
Consulting rarely offers perfect information.What to look for
Framing the decision, using proxies and assumptions, testing sensitivity, being transparent about uncertainty, and updating when better data arrived. - 4
How do you make sure your analysis is MECE?
Why ask it
Mutually exclusive, collectively exhaustive structuring is standard consulting practice.What to look for
An understanding that categories should not overlap and should cover the whole problem, with an example of an issue tree or framework they built, and awareness that frameworks are tools rather than answers.

Client Handling and Communication
Consultants succeed only if clients trust them and act on their recommendations.
- 5
How do you build credibility with a senior client who is sceptical of consultants?
Why ask it
Client scepticism is common.What to look for
Listening and learning the business first, using their language, delivering a quick useful insight, being honest about what they do not know, and following through reliably. - 6
Tell me about a time you presented a recommendation the client did not want to hear.
Why ask it
Shows courage and diplomacy.What to look for
Grounding it in evidence, previewing it with key stakeholders before the big meeting, framing it around the client's goals, and offering a path forward. Respecting the client's final decision. - 7
How do you structure a slide or email for a busy executive?
Why ask it
Clear, top-down communication is a core consulting habit.What to look for
Answer first, then supporting points, then detail. Action titles that state the message, one idea per slide, and a clear ask or next step. - 8
A client keeps adding requests outside the agreed scope. How do you handle it?
Why ask it
Scope creep hurts margin and team morale.What to look for
Acknowledging the request, checking it against the statement of work, discussing trade-offs or a change order with the engagement lead, and keeping the relationship positive. - 9
How do you work with client staff who feel threatened by your project?
Why ask it
Consultants often meet resistance from the people they need help from.What to look for
Involving them early, crediting their knowledge, being open about the purpose of the work, and avoiding surprises. Escalating through the sponsor only when needed.
Delivery and Teamwork
How the candidate gets work done on tight timelines with changing teams.
- 10
Walk me through a project you delivered from start to finish. What was your specific contribution?
Why ask it
Separates personal contribution from team output.What to look for
Clear context, their role, the analysis or deliverables they owned, how they handled obstacles and what changed for the client. 'I' where it was them, 'we' where it was the team. - 11
How do you prioritise when you have three urgent deliverables due on the same day?
Why ask it
Consulting workloads are intense.What to look for
Clarifying real deadlines and importance with the manager, doing a good-enough first version where quality allows, asking for help early, and flagging risks before they become misses. - 12
How do you check your own work before it goes to a client?
Why ask it
Errors in front of clients damage credibility.What to look for
Sense-checking numbers, tying totals, checking sources, reading slides as the client would, and asking a colleague to review important outputs. - 13
Tell me about a time you disagreed with your manager on a project.
Why ask it
Tests professional challenge.What to look for
Raising it privately with evidence, listening to their reasoning, agreeing a way forward, and supporting the decision in front of the client.
Motivation and Situational Questions
Why consulting, and how the candidate behaves when things go wrong.
- 14
Why consulting, and why our firm?

A deliberate approach: annual reports, industry research, talking to experts, building a glossary, and asking good questions early.
Running the interview well
- 1Use a short case or estimation question for every candidate so you can compare structure, not just stories.
- 2Interrupt gently with new information during a case to see how they adapt.
- 3Ask for the candidate's own contribution in every project story.
- 4Judge communication as you go: is their answer top-down and easy to follow?
- 5Run a client role play, such as a sceptical executive or scope creep, for client-facing roles.
- 6Be explicit about travel, hours and the type of consulting so candidates self-select honestly.
- 7Avoid over-rewarding framework jargon; the best candidates adapt structures to the problem.
Common questions
What questions are asked in a consultant interview?
Most consulting interviews combine case or problem-solving questions with behavioural questions about client handling, teamwork, leadership and motivation. Some firms also include estimation questions, written exercises or presentations.
How do I prepare for a consulting case interview?
Practise structuring business problems out loud, doing quick maths without a calculator, and summarising answers top-down. Practise with a partner and review each case for where your structure broke down.
How do I answer 'Why consulting?'
Give two or three genuine reasons, such as solving varied problems, learning quickly and working with clients, backed by an experience. Then explain why this firm specifically, based on its sectors, type of work or people you met.
What does a consultant do day to day?
It varies by firm and project, but typically includes client meetings and interviews, data analysis, building models and slides, workshops, team problem-solving sessions and status updates with the client.
What skills do consultants need?
Structured problem solving, comfort with numbers and data, clear writing and presenting, client handling, teamwork and the ability to learn new industries fast. Specialist consultants also need deep domain or technical knowledge.
What should I ask at the end of a consulting interview?
Ask about the types of projects new consultants work on, how staffing decisions are made, what training is offered, and what the interviewer enjoyed most about a recent project.
