I applied through a recruiter. The process took 6 weeks. I interviewed at Google (Mountain View, CA) in Feb 2015
Interview
Contacted a Google PM recruiter. He scheduled an interview. Came in for 6 on-site interviews, back-to-back, ranging from PMs, to UX manager, to engineering/technical, to PM director. Got called back that I didn't get the role, but it was close and I should try again in a year.
Interview questions [1]
Question 1
Describe something that you disagreed with executive management on and how did you convince them to change their mind.
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.
