Oliver Wyman interview questions

Standard consulting interview process — initial application, online assessment, first-round case + behavioral, final round with two cases and a partner conversation. The cases were market-sizing-shaped early, then more open-ended in the final round. They care about how you structure ambiguity more than whether you reach the "right" answer. Walk them through your thinking out loud. They'll redirect if you go off-track. Behavioral questions were standard — why consulting, why OW specifically, tell me about a time you led without authority. They push on specifics. Don't give them general answers. The partner round was conversational rather than evaluative — by that point they've decided. Treat it as relationship-building. Interview Question: How would you size the Australian market for electric scooters? Answer: Standard approach — population, urban density, addressable user base, willingness to pay, segment by ridership patterns vs. ownership. The structure matters more than the number.

After CV screening, I had a small introductory call with a partner. I was scheduled for a interview day about 1 and half months afterwards. They do both rounds of interviews in a single day, at the office. First round (2 interviews) in the morning, and, if you pass, second round (3 interviews) in the afternoon. All 5 of them include fit (15min) + case (30min). Fit is very similar every single time.
