Most Common Interview Questions and Example Answers

Tell me about a time you analysed a complex business problem

Example answer (STAR): Our company faced declining margins. I structured the problem into revenue and cost drivers, gathered data, and built a model. I identified that our product mix was shifting toward lower-margin items. I presented recommendations and we adjusted our strategy. Margins improved. I learned that complex problems become manageable when you structure them and use data. I apply that approach to consulting-style problems.

Tell me about a time you had to present to senior stakeholders

Example answer (STAR): I had to present a recommendation to our executive team. I prepared a clear narrative, supported it with data, and anticipated questions. I kept the presentation concise and focused on implications. They approved the recommendation. I learned that senior audiences want clarity, evidence, and clear next steps. I've since presented to clients and internal leaders with the same approach.

Why consulting? Why Oliver Wyman?

Example answer: I want to work on high-impact problems across industries and develop deep expertise. Consulting offers that breadth and depth. Oliver Wyman stands out for its industry focus and analytical rigour. I value the opportunity to work on complex problems with talented people.

What are your strengths?

Example answer: I'm strong in structured problem-solving and analytical rigour. I can break down complex issues and communicate clearly. I work well in teams and take ownership of my contribution. I've demonstrated the ability to deliver impact in ambiguous situations. I'm curious and enjoy learning about different industries. I aim to contribute to client success and team growth.

Tell me about a time you had to work with incomplete data

Example answer (STAR): We had to make a recommendation with limited data. I identified what we knew and didn't know, made reasonable assumptions, and documented them. I presented the analysis with appropriate caveats and suggested next steps to validate. The client appreciated the transparency and we refined the approach as more data became available. I learned that good judgment means acting with incomplete information while being clear about limitations.
