I applied online. The process took 3 weeks. I interviewed at Criteo (Paris) in Feb 2020
Interview
- Entretien téléphonique avec une RH pour discuter du parcours
- Un test de 30 mins en ligne (Questionnaire très simple de code, avec des questions générales)
- Un coding challenge en ligne. Un intervenant de Criteo vous demande de coder un exercice algorithmique et vous pose quelques questions sur votre exercice et les axes d'améliorations
- Une journée entière d'entretiens techniques (2 exercice algorithmique, 1 exercice système, 1 exercice culture fit)
Interview questions [1]
Question 1
Coding Challenge : Créer un algorithme qui permet de grouper des anagrammes entre eux, dans l'ordre d'apparition.
Ex : dad, ada, abc, bca, cba, xyu
=>
aad => dad, ada
abc => abc, bca, cba
uxy => xyu
HR screening and then some coding rounds with your lc questions, the questions weren't the hardest ones but I wasn't really prepared as for myself. Interviewers are overall fairly nice but it can vary, I notably had a bit more trouble with an interviewer whose english wasn't very good. But process itself was ok.
The process included 1 HR screening, 2 live coding interviews testing algorithms and problem-solving. They are classic leetcode questions. Then 1 system design interview and 1 final review with behavioral questions

Question 1
For live coding, there were classic leetcode questions
I applied through college or university. The process took 2 days. I interviewed at Criteo (Cyprus Heights, UT) in Sep 2022
Interview
The interview process was structured and professional, consisting of multiple stages including a technical test, coding interview, and behavioral questions. Recruiters provided clear guidance and timely feedback, making the overall experience positive and transparent.
