I applied online. The process took 3 weeks. I interviewed at Criteo (Grenoble) in Mar 2017
Interview
1 skype interview
2 on-site technical interviews
1 on-site system design interview
1 on-site "cultural fit" interview
Questions were less difficult then I "feared" but this was still a challenge.
My recommandations:
- keep attention to details, but don't loose yourself into details. people want to see your ability to solve problems, not your Java / C++ syntax skills. Focus on logic, not on syntax, not even on edge cases.
- always keep talking, explaining what you are doing
- be honest: my interlocutor thought that my solution was 100% working, I had to argue that there were still pieces missing. I guess this was appreciated.
- system design: know your figures and basic maths. I lost myself into stupid calculations.
- don't overdress!
- be careful with "cultural fit" interview (the last of the series): it's not just a chat with a future colleague, it's still a way to test your profesionalism
