Management Consulting Interview Questions: Case and Fit Interviews (2026)

The short answer: management consulting interviews have two parts. Fit interviews (McKinsey calls them the Personal Experience Interview) ask for detailed stories about your impact, leadership and how you handle challenges. Case interviews give you a business problem, such as whether a client should launch a product or why profits fell, and test how you structure it, analyze data, do quick math and reach a recommendation. Prepare four to six strong stories, practice 20 or more cases out loud with a partner, and get fast at mental math. Below is how each part works, the fit questions to prepare, a case method with a worked example, and how to use AI to prepare.

How consulting interviews work

McKinsey’s own interview page describes the process for most client-facing roles: “you will participate in a personal experience interview, followed by a problem-solving interview.” Many consulting roles also start with an online assessment; McKinsey’s is a gamified problem-solving test called Solve.

• Fit or personal experience interview: detailed stories from your past.
• Case or problem-solving interview: McKinsey says it will “present a business case to evaluate your analytical thinking and approach to solving complex problems.”
• More than one round: usually several interviews per round, each combining fit and case questions. Your recruiter will confirm the format.

Other firms, such as BCG and Bain, follow a similar mix of case and fit interviews, with their own formats. Check each firm’s careers site.

Fit interview questions

McKinsey suggests “coming prepared with two personal examples” for each of the areas it assesses, focusing on “your specific role” and “the key actions that were critical to success.” Prepare stories for questions like these:

Motivation

• Why consulting?
• Why our firm?
• Walk me through your resume.

Leadership and influence

• Tell me about a time you led a team through a difficult situation.
• Tell me about a time you persuaded someone who disagreed with you.
• Tell me about a time you changed someone’s mind without authority.

Impact and drive

• Tell me about your proudest achievement.
• Tell me about a time you set yourself an ambitious goal.
• Tell me about a time you had to overcome an obstacle to deliver a result.

Working with others

• Tell me about a time you worked with someone difficult.
• Tell me about a time you helped someone else succeed.
• Tell me about a time you failed.

Consulting interviewers go deep: expect follow-ups on every step (“What exactly did you say?” “What did they say back?”). Use the STAR method, keep the situation short, and spend most of the time on your actions and your reasoning. See also our guides to leadership and teamwork questions.

How to approach a case interview

1. Listen and clarify. Restate the problem and the goal: “So the client wants to know whether to enter the market, and success means profit within three years?” Ask about anything unclear.
2. Structure. Take a minute to build a clear framework, usually an issue tree that breaks the question into parts that don’t overlap and cover the whole problem. Walk the interviewer through it.
3. Prioritize and analyze. Start with the branch most likely to answer the question. Ask for data, interpret charts, and do the math out loud.
4. Synthesize as you go. After each piece of analysis, say what it means for the answer.
5. Recommend. Give a clear answer, the two or three reasons, the risks, and the next steps.

Worked example

An illustration, not an actual firm’s case.

The case: “Our client, a regional coffee chain with 200 stores, has seen profits fall 20% over two years while revenue stayed flat. Why, and what should they do?”

• Clarify: Profit fell and revenue is flat, so costs must have risen. Is the fall across all stores or some? Any changes in the business?
• Structure: Profit = revenue − costs. Revenue: customers × average spend (flat, but check the mix). Costs: ingredients, labor, rent, other. Also check by store type and region.
• Analyze: The interviewer shares data showing labor costs up 25%, driven by longer opening hours added two years ago. Stores open after 8 p.m. do very little business in those hours.
• Math: If each store added 3 hours a day with two staff at $20 an hour, that’s 3 × 2 × $20 = $120 a day, about $44,000 a year per store, or about $8.8 million across 200 stores.
• Recommend: “Cut evening hours in stores where late sales don’t cover the added labor, which recovers most of the lost profit. Keep late hours in the few high-traffic stores. Risk: some customers may switch to competitors; test in 20 stores first and track sales.”

Market sizing

Market sizing questions ask you to estimate a number, such as “How many coffee cups are sold in the US each day?” Interviewers care about your logic, not the exact number:

1. Choose an approach (top-down from population, or bottom-up from stores).
2. State assumptions clearly and round numbers for easy math.
3. Calculate step by step out loud.
4. Sanity-check the result.

How to prepare

• Practice 20 or more cases out loud with a partner, ideally someone who has been through consulting interviews. Firms such as McKinsey publish sample cases on their sites.
• Drill mental math: percentages, growth rates, break-evens, and big numbers.
• Write and rehearse your fit stories until you can tell each in two minutes and answer deep follow-ups.
• Read business news so you can discuss industries and trends.

Using AI to prepare

McKinsey is explicit that using AI to practice interview questions or explain frameworks is “encouraged,” while “generating real-time answers during an interview” and using AI during assessments (unless specifically permitted) are not allowed. So use AI to generate practice cases and critique your structure, but not during the real thing. See our guide to AI prompts for interview practice.
