Format
What the Oliver Wyman assessment centre looks like
First Round — Case Interview
40-50 minutes1 interviewer (Manager/Principal)
Candidate-led case interview. You receive a business problem and work through analysis, data interpretation, and recommendation.
First Round — Experience Interview
30-40 minutes1 interviewer
Behavioural interview testing leadership, personal impact, or problem-solving. Similar to McKinsey's PEI format. Deep dive into one story for 15-20 minutes.
Final Round — Case Interview
40-50 minutes1 Partner
Harder case with more ambiguity. Partners probe your assumptions and test your ability to think under pressure with incomplete data.
Final Round — Experience Interview
30-40 minutes1 Partner
Deeper experience interview with more senior interviewers. Tests cultural fit, maturity, and self-awareness alongside leadership evidence.

Avoid
Common mistakes at Oliver Wyman assessment centres
Jumping to conclusions in case interviews without laying out a structure first. Always pause, structure your thinking, then proceed.
Having only one anchor story. Different interviewers test different competencies — prepare at least 3 distinct examples.
Not asking clarifying questions at the start of a case. Good candidates confirm understanding before diving in.
Failing to synthesise at the end. Partners want a clear recommendation, not just analysis. State your answer, then support it.
Being thrown by unexpected case types. Practise market sizing, profitability, market entry, and M&A cases.
Treating the experience interview as less important than the case. It carries equal weight.
