I applied through an employee referral. The process took 4 weeks. I interviewed at Oliver Wyman (London, England) in Oct 2018
Interview
Common consulting interview process with three stages each with 2/3 interviews. Main focus on statistical and guesstimation cases with many mental calculations. 2 cases in first 3 interviews (1 motivational based), 3 cases in second round and 2 pure brain teaser interviews in last stage
Interview questions [1]
Question 1
Walk me through a situation in which you showed leadership skills.
it was smooth but you need to work hard on your calculations skills, i failed in this part of the case because the calculator is not allowed and i had not familiarize myself with it before the interview but overall it was a good experience
Interview questions [1]
Question 1
tell me about yourself, why consulting and the case question
I applied online. I interviewed at Oliver Wyman (Milan) in May 2026
Interview
Pre-selection with one mini-case/brain teaser of 30 min. Overall, the case was testing both numerical reasoning and logics I would say. If you prepare the mini cases correctly you can pass.
Interviewers never attended on time. Rescheduled 7 times. Cases were easy relative to other firms. They dont take candidates very seriously so prepare for that. Personal questions include why OW?
