Top McKinsey & Company Interview Questions
(2025 Guide)
McKinsey & Company is the world’s most prestigious management consulting firm — known for shaping corporate strategy, advising governments, and launching the careers of Fortune 500 CEOs. But getting in? That’s a different game. The McKinsey interview process is unlike traditional tech or product interviews. It blends structured behavioral evaluation with a highly analytical problem-solving case study format. Whether you're applying as a generalist consultant, business analyst, or a specialist (e.g., digital, implementation, design), you’ll be tested for communication, mental agility, and structured thinking under pressure. This guide gives you a comprehensive breakdown of the McKinsey interview experience — and how to master it with preparation, frameworks, and mock practice.
Why McKinsey & Company Interviews Are Unique
While other firms ask about your resume or throw technical curveballs, McKinsey focuses on: Structured problem solving: Can you break a vague business problem into logical pieces? Hypothesis-driven thinking: Can you make data-backed assumptions and refine them on the fly? Client readiness: Can you speak with poise, clarity, and empathy — as if you were already on a client site? Behavioral impact: They don’t just want smart people — they want people who influence, inspire, and take ownership. Their two main tools for evaluating this: PEI (Personal Experience Interview) and the Case Interview.
Roles McKinsey & Company Hires For
- Business Analyst (BA): For undergraduates or those with 0–2 years experience. Fast-paced learning and exposure to multiple industries.
- Associate: For MBAs, PhDs, or experienced professionals. You're expected to lead workstreams and own client interactions.
- Digital & Analytics (McKinsey Digital): Engineers, data scientists, or product managers embedded in strategy teams.
- Implementation Consultant: Operational roles focused on change management, transformation, and on-the-ground execution.
- Design & Research (McKinsey Design): Strategists and designers solving user-centric business problems.
Process Overview
The process usually takes 2–4 weeks and consists of:
Online Application or Referral
Include resume, transcripts, and cover letter. Referrals help immensely, especially at core schools.
PST or Solve Game (screening)
Some roles include McKinsey’s Problem Solving Game — a gamified logic and attention test.
First-Round Interviews
2–3 back-to-back interviews, each with a case + PEI portion.
Second-Round / Final Interviews
Typically with partners. Higher emphasis on leadership, insight generation, and case pushback.
Offer Call
Recruiter will walk you through compensation, timeline, and start date.
Interview Rounds
Case Interviews
McKinsey cases are interviewer-led, meaning you won’t be in charge of navigating the case from start to finish. Instead, the interviewer will walk you through a structured problem with a series of questions. You’ll be expected to clarify the prompt, structure the problem, do math, synthesize insights, and make a final recommendation.
Tip: Use frameworks, but customize them. Speak clearly and summarize what the data suggests often.
PEI (Personal Experience Interview)
The PEI is not a warm-up — it’s 50% of your interview. You’ll be asked to describe one high-impact story in detail, with deep follow-ups.
Tip: Build 3–5 STAR stories (Situation, Task, Action, Result) and practice going 3–4 layers deep on follow-ups.

Record yourself giving 1-minute recommendations.
Write and practice PEI stories (STAR).
Read McKinsey cases and partner-level feedback online.
Get comfortable with ambiguity — that’s the real test.
McKinsey interviews are not about perfection. They’re about clarity, structure, presence, and curiosity. They want people who can handle high-stakes ambiguity while keeping their composure and bringing insight to every conversation. The best prep? Practice speaking like a consultant — out loud. Get feedback. Iterate. And remember: every great consultant was once a nervous candidate.
