Criteo interview questions

The interview process had multiple steps starting with a phone interview. During the phone interview, my recruiter first told me about the company and it's culture in greater detail. In addition, she described how this position fits into their current operations. From there, she was able to answer all of my questions and then asked me for some information regarding my past experience, and how my skills could be transferable to this role. Once we concluded our conversation on the phone, I was emailed a few days later to book an in person interview. The in-person interview was with the department manager and a team lead at the same time. I preferred the 2 on 1 style of interview because it was efficient, it gave me a better idea of their dynamic departmentally, and how my role would fit in the department. The interview was very positive, and they were able to extend an offer to me the next day. When I accepted the team was immediately very welcoming and accommodating to my needs.

There were three interview phases after I submitted my application. First I was called by a local talent management person (aka recruiter) and we set up a half hour interview in which he talked me through what Criteo did and asked some basic questions. Next I was invited to a video coding interview. This was done on Skype but we used an online code collaboration tool for the coding. It was basically a text editor since they were testing my ability to think and talk about algorithms. No compiler was used to check my code. The final stage took 4 hours in the office: two 1 hour sessions of whiteboard coding, 1 session of system design, and then an interview with the hiring manager. I also got a nice guided tour. The overall process was very smooth. It took longer than expected because of the Christmas holidays. The people I talked with were amazingly helpful throughout. Check out their web site since the process is well documented there.
