I applied through a recruiter. I interviewed at Google (Boston, MA) in Nov 2015
Interview
I chatted briefly with a recruiter who initially contacted me saying my experience looked like a PM position might be a good fit for me. I was then interviewed by a current google PM over an *extremely* bad connection in which I could hear my own voice repeated back to me at a .5 sec delay. Not sure if I was on speakerphone or what, but it was annoying and prohibitive.
Interview questions [1]
Question 1
How many elevators should an average office building have.
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.
