McKinsey & Company
Business Analyst
This is a demo case file: a realistic example written from commonly known interview formats, not a real candidate's interview experience.
Questions asked
- A client's regional coffee shop chain is losing profitability — how would you diagnose it?
- How would you estimate the market size for electric scooters in a mid-size city?
- What clarifying questions would you ask the client before doing any analysis?
What to expect
Wanted a structured framework stated up front before any numbers. Appreciated clarifying questions early. All math had to be done out loud, and they nudged me back on track twice when I went down a rabbit hole.
