We’ve seen Oliver Wyman evaluate Data Analyst candidates less like a pure analytics role and more like a consulting apprenticeship. Multiple candidates reported that the strongest signal was not technical depth, but clear business reasoning under pressure: being able to structure a messy problem, explain tradeoffs, and defend a recommendation without getting lost in the weeds. Even the case described as “not especially complicated” still rewarded candidates who could think aloud in a disciplined way and connect analysis back to a client-style decision.
A recurring theme is that Oliver Wyman also pays close attention to how candidates talk about their own work. Our candidates report repeated questions about prior projects, relevant analytical experience, and leadership examples, which suggests they want people who can translate individual contributions into a broader business narrative. The take-home project presentation adds another layer: it’s not just about getting the right answer, but about how convincingly you can present the work and handle follow-up questions. That combination tells us the firm is screening for structured communication and executive presence, not just spreadsheet fluency.
What makes this process distinctive is how consistently it blends case thinking with personal fit. Candidates who did well seemed to understand that the interviewers were looking for someone who could operate comfortably in a client-facing environment, where clarity matters as much as analysis. The relaxed tone described by one candidate may make the process feel approachable, but the underlying bar is still high: can you make a business argument that is coherent, concise, and credible?

Real interview reports from people who went through the Oliver Wyman process.
There were 2 rounds of interviews, and the process felt very consulting-heavy from the start. The first round was two back-to-back 30 minute interviews: one case interview and one behavioral interview. The case was a general business case and leaned much more on reasoning than on anything overly technical, so it was not especially complicated if you had practiced a bit beforehand. The behavioral side was pretty standard and focused on my background, including questions like talking through my previous projects and relevant analytical experience. The recruiter I spoke with was also very young and easygoing, which helped keep the tone relaxed.
The second round followed the same pattern but added a take-home project presentation and Q&A. I was given the project about a week in advance, along with a dataset and a set of questions to work through. After that, I had another case interview and another behavioral interview, including questions about why I wanted to join Oliver Wyman and my leadership experience. Overall, the process was structured but fair, and the main thing they seemed to care about was how clearly I could think through a business problem and explain my reasoning. I’d say the best preparation is to practice consulting-style cases and be ready to walk through your past projects and leadership examples clearly, since those came up directly.
Prep tip from this candidate
Practice general consulting business cases with a focus on clear reasoning, since the cases were described as more about logic than difficulty. Also prepare to present a take-home dataset analysis and answer questions on your past projects, leadership experience, and why you want Oliver Wyman.

The process starts with an initial recruiter conversation that sets the tone for a consulting-heavy interview loop. This screen is described as relaxed and easygoing, and it helps confirm your background and fit for the role.
The first round consists of two back-to-back interviews: one general business case and one behavioral interview. The case focuses more on reasoning and structured thinking than technical depth, while the behavioral portion covers your background, previous projects, and relevant analytical experience.
The second round follows the same case-plus-behavioral format, but adds more emphasis on motivation and leadership. Expect questions about why you want to join Oliver Wyman, along with deeper discussion of your leadership experience and how you approach business problems.
Before the second-round discussion, you receive a dataset and a set of questions about a week in advance. You then present your take-home project and answer follow-up questions, which tests how clearly you can explain your analysis and reasoning.
