I applied through an employee referral. The process took 4 weeks. I interviewed at Google (Palo Alto, CA) in Jun 2015
Interview
Started with one phone interview with a Product Management recruiter (very friendly), then 4 weeks later 3 interviews with PMs from different areas of the company. The first 2 were challenging but PMs wanted to be part of your thought process. 3rd interview was a lot more technical, with "estimates" questions and hard to follow.
Interview questions [1]
Question 1
How would you reduce bandwidth consumption in search when users from third 3rd world countries search?
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.
