J'ai postulé via la recommandation d'un employé. Le processus a pris 3 mois. J'ai passé un entretien chez Google (Mountain View, CA) en mai 2012
Entretien
After a referral from a current employee, it was a long process (3 months). Long enough, in fact, that the job listing itself changed several times over the course of the process. An initial call from a recruiter, two (1hr.) technical phone interviews covering some basic data analysis, technologies, and relevant items from the resume. Invited to fly out for a on-site in Mountain View, involving 4 interviews with analysts from different business segments. Took a few weeks to get an answer after that.
Questions d'entretien [1]
Question 1
There was one with 'what-if' questions involving how to analyze certain aspects of their business, including finding trends in ad bidding behavior and detecting contextual advertisers who were gaming the system. Open-ended enough that it wasn't clear if a right answer existed, but they may have had one in mind.
- Asked foundational questions about key definitions and terminology to assess baseline understanding of core concepts
- Completed a timed online coding assessment covering practical programming challenges and problem-solving ability
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.
