I applied through a recruiter. The process took 4 weeks. I interviewed at Google (Mountain View, CA) in Apr 2015
Interview
The process was quite involved. It started a 3 rounds of phone interviews and then I was finally invited to come up to Google HQ for an onsite interview. I arrived on site and met with the HR coordinator first and then a series of other Google PMs who spent about an hour each with me. There were no algorithm questions but al lot of open-ended product design questions
Interview questions [1]
Question 1
A number of "product design" questions such as "How would you design ....". The goal was to access my thought process and problem solving skills
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.
