I applied online. I interviewed at Oliver Wyman (London, England) in Jan 2011
Interview
CV screening --> numeracy and logic reasoning test --> CV screening --> first round interviews (case + CV) --> second round interview (case + CV)
People were wonderful - best firm I've ever interviewed with. Very down to earth, unlike some arrogant competitors.
They host a dinner for people shortlisted for the second round, then a dinner for offerees. Great chance to meet employees and ask them about the company.
Interview questions [1]
Question 1
The usual brain teasers - no need to prepare in advance.
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
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?
Application
I applied through an employee referral. The process took 4 weeks. I interviewed at Oliver Wyman (Zürich)
