I applied through a recruiter. The process took 6 weeks. I interviewed at Google (Mountain View, CA) in Jun 2016
Interview
I was not looking for a job, but a Google recruiter reached out to me on LinkedIn, so I bit. I passed her phone screen and then the subsequent phone interview with a product manager. Then, I had 3 on-site interviews with other product managers. I thought 1 went very well, 1 went medium well, and 1 went just ok. I then had lunch with another product manager, which was also kind of blah. After lunch, I met back up with my interview coordinator, and he said they didn't have any more questions for me, so I could go. From what I could tell, that was neither good nor bad, but it turned out to be bad, because I got the news the next day that they weren't going to move forward with my candidacy.
Since I agreed to the NDA, I won't post the exact interview questions here, but I was surprised that all 3 of my on-site interviews each centered around one problem-solving/product design question. There were pretty much no behavioral questions.
Interview questions [1]
Question 1
Such and such governmental organization/department is "broken." How would you fix it?
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.
