J'ai postulé en ligne. Le processus a pris plus d'une semaine. J'ai passé un entretien chez Google (New York, NY) en déc. 2014
Entretien
I was contacted by a recruiter, who sent me a series of questions that I answered in print. After that I was contacted to set up a phone interview. A current quantitative analyst was the interviewer. She went right into the the interview questions and stopped right at 30 minutes. The interview consisted of technical statistical questions, a thought experiment, then time for me to ask questions.
- 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.
