I applied online. The process took 6 months. I interviewed at Oliver Wyman (Brussels) in Apr 2023
Interview
First a CV screening then cases. There were two cases, one on an M&A question, one about a calculation. The consultants screening me were nice, but I was simply not prepared well enough.
Interview questions [1]
Question 1
They ask you to speak a language that you're not used to speaking, for me, this was a question about my vacation in French.
