Candidates describe Oliver Wyman interviews as friendly in tone but demanding in content. The core is the case interview, and market sizing and estimation come up again and again: taxi costs in a US city, petrol stations in Athens, rice consumption in the UK. Interviewers appear to care more about how you structure the problem and state assumptions aloud than about a perfect number. One candidate was told that frameworks would not help much.
Formats vary. Business Analyst candidates report a pre-interview assessment or online case, a combined 30-minute behavioral and 30-minute case block with a spreadsheet to present on screen, and a final round with a business case, a written case and behavioral questions. In the written case, one candidate had 30 minutes to prepare a presentation from the materials given. Another described an online assessment with two 30-minute cases, then a day of four interviews. Several consultant-level reports mention a longer final day or a presentation to senior leaders.
Expect data-reading skills too. One candidate was asked which data in a loan case mattered, and another faced an IRR question in a super day. Fit questions are consistent across reports: why Oliver Wyman, why consulting, prioritizing competing commitments, and a time you led or failed. Prepare specific answers rather than generic praise. Outcomes were mixed, and the reported business analyst experiences were mostly rejections, so rehearse aloud and treat fit as seriously as the cases.

Real interview reports from people who went through the Oliver Wyman process.
First round consisted of a business case and a behavioral interview. Business case was typical consulting case and the behavioral was tailored towards experiences that demonstrate your ability to exercise skills consultants must have: balancing priorities, handling a lot of information, etc. Final round consisted of a business case, written case, and behavioral. Business case was typical. Written case was similar to business case but you were given everything all at once and had 30 minutes to prepare your presentation. Behavioral was very normal. Not interesting and didn't seem like they learned a lot about the person. It was very professional.
Questions asked: As a consultant, you'll often ahve many competing priorities? Tell me about a time you had to balance multiple commitments when you couldn't do everything.

Synthesized from candidate reports. Individual experiences may vary.
Candidates report starting with a pre-interview assessment or online test. One described a roughly 30-minute solo business case, and another two back-to-back 30-minute online cases covering market entry and risk. Some candidates instead report an HR screen first, so the order may vary.
Business analyst candidates describe a first round combining a case with behavioral questions, sometimes in one hour-long block. One candidate worked a spreadsheet beforehand and then presented findings by screen share. Behavioral questions typically probe prioritizing tasks, balancing competing commitments, and why Oliver Wyman.
Some candidates report more case interviews before the final stage. One was invited to a 'How to crack the case' workshop before two business case interviews, including market sizing and a loan-data case. Others describe several rounds, some with senior interviewers. Expect estimation and data interpretation.
Final stages are commonly described as several back-to-back interviews. A business analyst candidate reported a business case, a written case and a behavioral interview. Other reports mention a four-interview day with three cases and a CV conversation, and occasionally a presentation, so the exact mix may differ.
