I applied online. I interviewed at Criteo (Barcelona (Spain)) in January 2018. There were two stages of this process (1) phone interview (2) in office interview: (1) the first stage consisted of two parts (a) role play and (b) culture fit interview. (a) The role play was an opportunity to sell one of four products to Criteo itself. This is an oppotunity to demonstrate your Sales skills. After which you discuss the role play and how you performed. It was a good idea and I enjoyed the role play. Also, my discussion after the interview was open and helpful. (b) The Culture fit was a nice opportunity to talk about the team and see if there is a good fit for you and the company and the spesific team to which you are applying. (2) the interview in the office was nice (and succesful). I sat down with the person with whom I did the role play, and two regional sales managers. I repeated the roleplay with them and it took 20 minutes. Afterw which we discussed the role play and how I did. For the remaining 30 minutes of the interview we just discussed the company the team, and my situation. This the a great (and the last) opportunity to see if you are a good fit for Criteo. Bonus: After the in-office interview the recruiter to whom I was talking showe me around the office. In sum, Criteo as a stright forward and easy to understand interveiw process. That both tests you for the role and helps you see if it is were you want to be. I have interveiwed many times and Criteo as a process that is actually quite simple and enjoyable.
