The interview was held in 4 meetings which lasted almost a month. At first I had an interview with recruiter, then with my position's manager, then with the person who was in the position I was applying for and last with hiring manager who is the manager of my manager. I have done a test project after I met with the recruiter and it was evaluated in the second interview. No one stressed me out during the interviews everyone was so friendly. The questions were almost the same in every interview. Finally I got hired and I'm very happy about Criteo.
