McKinsey & Company mock interview: how to practice

The McKinsey & Company interview format

McKinsey & Company works in management consulting, and its interviews center on case interviews plus fit and behavioral questions.

Mock interviews work because they turn that format into reps with feedback, which is the only thing that reliably improves performance under pressure.

What a good mock interview covers

Aim to reproduce the real conditions, not just the questions:

• Practice market sizing and estimation.
• Practice profitability and root-cause cases.
• Practice market entry and growth strategy.
• Practice fit questions on leadership, teamwork, and impact.

How to run your mock interviews

You can practice two ways, and doing both is ideal:

• With a partner: one person interviews, the other answers, then you swap and give honest feedback.
• Solo with an AI interviewer when no partner is free, so you can get reps and a score any time.
• Record or note your answers so you can see patterns and fix the same mistakes.

How to prepare for McKinsey & Company

A few things to focus on before the real thing:

• Practice structuring ambiguous problems into clear, mutually exclusive buckets before diving in.
• Drill mental math and estimation so you can run numbers out loud without losing the thread.
• Always land on a clear, defensible recommendation with the reasons behind it.
