I applied through an employee referral. I interviewed at Oliver Wyman
Interview
Quite fast process, laster 1.5 month for 4 interviews. Difficult cases but not unsolvable. The interviewers were always trying to help and understanding. The response of the support staff was always quick and on-point
Interview questions [1]
Question 1
How many ATMs are needed for a remote island in Greece?
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?
