J'ai postulé via la recommandation d'un employé. Le processus a pris 3 semaines. J'ai passé un entretien chez Google (Mountain View, CA) en oct. 2019
Entretien
The onsite interview is 4 rounds of 45 minutes back-to-back. (1) Self introduce (2) Statistical concepts (3) Question related to probability and recursion (4) Machine learning use case. There was a lunch break where the food is not impressive.
Questions d'entretien [1]
Question 1
How to build a model to predict user behavior
A/B test
30 minute phone screen with HR, followed by an interview with the hiring manager. HR would not even provide a salary range for the role, which was very weird. The HR rep was not familiar with the role and seemed to be reading from the JD when I asked questions about it.

Entretien
5 interviews, 1 call with a recruiter, followed by technical interview then three on-site (now hangouts). The call went well. The interviewer was about 10 minutes late and so he didn't even do introductions and stuff. He jumped straight to questions. Fortunately, the 4 questions were not very hard so I finish just in time.
