Applied online for Dubai Office, OW Dubai organized a recruitment event in Paris, I was invited to the event and the interviews. There where 2 intervies (with senior consultants) and 2 with partners if you passed the first round.

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
