Oliver Wyman Analyst Interview: Complete Guide
Oliver Wyman cases go math-first — expect to quote basis points, loss ratios, and combined-ratio mechanics in your head, no paper. Two candidate-led rounds weighted toward financial services (NIM, capital, underwriting P&L). Hand-waving a recommendation in dollars when the interviewer asked for bps is how strong candidates still fail.

Sample Oliver Wyman Cases
Case 1: A European retail bank wants to raise its net interest margin by 40 basis points…
Prompt: A European retail bank wants to raise its net interest margin by 40 basis points over two years without losing deposit share. How would you approach it?
How to structure: Oliver Wyman cases reward quantitative rigor. Decompose NIM into asset yield, deposit cost, and mix. Size the gap in bps contribution per lever. Expect the interviewer to ask for a direct number early — don't qualitatively hand-wave.
Case 2: A mid-sized P&C insurer is considering entering the cyber insurance market. Thei…
Prompt: A mid-sized P&C insurer is considering entering the cyber insurance market. Their CEO wants a recommendation in six weeks. Go.
How to structure: Candidate-led. Structure around market attractiveness (growth, loss-ratio dynamics), right-to-win (data, underwriting expertise), and capital impact (reserving, reinsurance). Oliver Wyman cases often probe on underwriting P&L mechanics — know loss ratio + combined ratio cold.

Common Mistakes in Oliver Wyman Interviews
- !Under-preparing mental math. OW's reputation for math-heavy cases is not a cliche — candidates who can't rapidly calculate percentages, ratios, and compound changes fail early.
- !Treating OW like a generic MBB. OW's practice concentration in financial services means industry-savvy answers outperform generic 3Cs / 4Ps in this room.
- !Rushing the problem statement. OW interviewers will clarify assumptions only if you ask — candidates who jump to structure without confirming the objective get walked back mid-case.
- !Weak synthesis under a finance lens. If the case is about NIM, your recommendation should end in basis points or dollars, not 'improve margin by streamlining operations.'
What recent Oliver Wyman candidates say
“I passed my 1st round case interview with Oliver Wyman for an internship position in Doha. I found it quite simple and pleasant. My next interview is next week on Tuesday with a Partner whose background is in Government and Public Affairs. Very similar to my professional background. I think it might be that it was done on purpose that they matched our profiles.”
“I am currently interviewing for an internship position at Oliver Wyman (Milan office) and I would like to have some insights about how the interviews are conducted. In particular, the next step will be the Team Assessment, what kind of problem will be asked to solve? Will it be an actual case? And concerning the cases, are they usually candidate-led or interviewer-led?”
How Oliver Wyman Differs
| vs. | How Oliver Wyman differs |
|---|---|
| Mckinsey | Oliver Wyman is candidate-led, not interviewer-led like McKinsey — you drive structure. OW cases are mathematically harder on average; McKinsey cases lean more on PEI and case-format precision. |
| Bcg | Both are candidate-led, but OW cases typically involve more quantitative depth (especially in financial services), while BCG cases lean toward broader strategic framing. OW has no Casey-equivalent gated assessment. |
