Consulting Fit Interview: Stories, Questions and Why Consulting

What is a consulting fit interview?

The fit interview is the personal half of a consulting interview: questions about your experiences, your motivation and how you work with people. At McKinsey, BCG and Bain it sits next to the case in most rounds, usually for 10-20 minutes. Candidates tend to over-prepare the case and under-prepare this half, even though a weak fit section can sink a strong case.

Each firm brands it differently. McKinsey calls it the Personal Experience Interview (PEI) and goes deep on one story. BCG runs a skills interview on experience and motivation. Bain covers motivation and personal qualities alongside its cases. The firm guides for McKinsey, BCG and Bain describe each process.

What McKinsey, BCG and Bain say they look for

Each firm publishes the qualities it assesses. Paraphrased from the official careers pages:

McKinsey renamed its dimensions in 2025. McKinsey's own careers site (its interviewing page for Japan, checked 18 October 2026) lists Connection, Drive, Leadership and Growth for the personal experience interview, with problem solving assessed in the case. Prep providers map them to the previous names: Personal Impact became Connection, Entrepreneurial Drive became Drive, Inclusive Leadership became Leadership, and Courageous Change became Growth. Some regional McKinsey pages still show the older wording, so use the names in your own invitation email if they differ.

The substance barely changes. Under either set of labels, McKinsey wants evidence that you influence people, push through obstacles, lead others and adapt when things go wrong. The same Japan page also lists problem solving and expertise among the qualities McKinsey assesses, so check the list in your own invitation.

"Tell me about yourself": a 90-second template

Answer "tell me about yourself" or "walk me through your resume" in about 90 seconds, in four blocks: who you are today, two quantified highlights, the thread that connects them, and why you are in this interview. At a normal speaking pace that is 200-230 words. The goal is to hand the interviewer two strong stories to probe, so pick highlights that match the firm's assessed qualities.

Worked example (fictional candidate). Joris is finishing a one-year master's in finance at a Dutch university after a bachelor's in econometrics. He is interviewing for a business analyst role.

"I'm finishing a one-year master's in finance in Rotterdam, after a bachelor's in econometrics. Two experiences outside class taught me the most. The first was a part-time pricing role at a meal-kit start-up. About 30% of new customers cancelled after their discounted first box, so I built a model comparing three discount structures and ran a four-week test with the marketing lead. The structure we chose cut first-month cancellations from 30% to 22%, and the company still uses it. The second was chairing our student investment association, which has about 120 members. After two years of falling membership, I interviewed twenty people who had left, found that the weekly sessions were too technical for first-years, and split the program into a beginner and an advanced track. Membership was back above 120 within a year. What links the two is that I like finding the number that explains a problem and then persuading people to act on it. Consulting lets me do that across many industries early in my career, which is why I am here today."

Why it works. The opening takes one sentence. Each highlight has a cause, an action and a before-and-after number, so the interviewer can pick either one for a full PEI-style probe. The first story signals drive and problem solving; the second signals connection and leadership. The last two sentences give the reason for applying and stop, which invites the next question. Replace every detail with your own experiences. Rehearse the four blocks and let the wording vary from one interview to the next.

Building a story bank: five stories that cover 90% of questions

Five well-chosen stories answer most fit questions at all three firms. Pick experiences in which you personally made a difference, under some pressure, with a result you can describe.

McKinsey's guidance of two examples per area means a second story for each of the first four. Mine each story with a short worksheet:

1. Write the setup in two sentences: context, your role, the stakes.
2. List three moments where you decided something, and why.
3. Write down one sentence you said to a person who disagreed with you.
4. Quantify the result (money, time, people, ranking).
5. Note what you would do differently today.

How to survive follow-up questions

Interviewers probe until the story runs out of detail, and that is where weak stories fail. McKinsey's prep page tells candidates to lead with their reasoning and focus on their specific role.

Two habits make stories hold up. First, say "I", not "we". Interviewers score what you did, and a story told in the plural gives them nothing to score. Our case interview mistakes article lists other common gaps. Second, keep the setup short (about 30 seconds) so most of the time goes to actions, reasoning and result. Expect follow-ups such as what exactly did you say, what did the other person reply, what other options did you consider and what would you change.

Stephan's note: From the interviewer's side of the table, a story becomes credible at the third follow-up. If you can still give the exact words you used and the alternative you rejected, the interviewer can score you with confidence.

"Why consulting?" and "Why this firm?": a worked answer

A strong answer connects three things in under two minutes: a past experience that drew you to the work, a concrete feature of consulting that matches it, and a specific reason for this firm. Bain lists a clear reason for choosing Bain among its criteria, so the third part carries weight.

Worked answer (fictional candidate): Sanne is finishing a master's in supply chain management at a Dutch university and interviewing with a strategy firm in Amsterdam.

"During my thesis I spent four months inside a Dutch food wholesaler, mapping why deliveries to supermarkets arrived late. I found that 60% of the delays came from one loading dock, and the operations director changed the shift schedule within a week. That speed from analysis to decision is what I want more of. Consulting gives me that across many industries in my first years, with people who are better than me at structuring problems. I am applying here because your Amsterdam office has a strong consumer and retail practice, and the two consultants I spoke to at the campus event described teams of three or four where juniors present to clients early. That matches how I learned most during my thesis."

The answer works because each claim is specific: a number, a decision, a practice area and a named reason drawn from conversations. Replace every detail with your own. The same logic drives a strong consulting cover letter, so draft both together.

Why McKinsey, why BCG, why Bain: what each firm says about itself

The most credible "why this firm" answer ties one thing the firm states about itself to one experience of yours and one conversation with its people. The table below is built only from each firm's own careers, purpose and values pages, checked on 19 October 2026 and paraphrased. It gives you the firm's own vocabulary; the conversations supply the proof.

Pick one row for your answer. A sentence such as "I value apprenticeship" is still generic, because every firm says it trains its people. It becomes specific when you add the consultant who described how a manager coached them through a first client presentation, and your own story of learning that way. BCG publishes its values themselves as an image on its purpose page, so the text above uses its five written principles.

The questions you ask at the end

Most interviews close with time for your questions. Ask about the interviewer's work, which shows curiosity and gives you real information. Good options:

1. What has surprised you most about the work since you joined?
2. How are juniors staffed onto their first projects in this office?
3. What separates the analysts who are promoted fastest?

Skip questions answered on the firm's website, and leave salary for the recruiter.

Common fit mistakes

1. Stories without stakes. A project that went smoothly proves little.
2. Group credit. Describing what "we" did hides your contribution.
3. Over-rehearsed delivery. McKinsey asks candidates to have a conversation, so practice the facts and let the wording vary.
4. Generic motivation. "I like solving problems" fits every job; name a specific experience.
5. Invented or inflated stories. Follow-ups expose them, and BCG's guidelines prohibit using AI to invent or exaggerate experiences.
