I applied through an employee referral. The process took 2 weeks. I interviewed at Criteo (Paris) in Nov 2018
Interview
Plusieurs entretiens techniques de coding, un de system design et un final. Entretien difficile mais gage de qualité, d'ailleurs boîte exceptionnelle, des gens brillants de partout, très bonnes conditions de travail.
I applied through a recruiter. I interviewed at Criteo
Interview
I did a remote interview, the engineers didn't present their self, they proposed an algorithm question immediately. I was able to solve it, I proposed the optimal solution, but i did not have time to implement, I was rushing against the time because they asked a lot of basic questions. Finally, I asked some questions which they didn't answer at all. The review was very aggressive and negative, I would not recommend anyone to pass an interview here. These engineers are expecting you to do a perfect solution.
