The process took 4 weeks. I interviewed at Google (Mountain View, CA) in Aug 2011
Interview
I have interviewed for several positions with Google. All of which would have essentially been lateral moves. Ironically, Google determined I was not technical enough for their teams.
Interview questions [2]
Question 1
If you have a vacant field and add one flower and the number of flowers doubles everyday and at the end of 45 days, the field is full, on what day is the field half full?
Very self-driven, first of multiple rounds, where I had to take the initiative to arrive at the problem, constraints, approach, solutions, tradeoffs and reasoning behind it in a matter of 30 minutes.
You would have to do a hiring assessment first, then a recruiter screening follows. First round interview with the hiring manager. Majorly product sense and product improvement. The questions were not direct though.
Overall a lot of steps to the interview process. Talked to different people and had opportunities to ask questions. Many different stages which made it a lengthy process overall. Wasn't too bad.
