I applied through an employee referral. The process took 3 weeks. I interviewed at Google (Mountain View, CA) in June 2015
Interview
The conversation was halting and not fluid. I couldn't really get comfortable with the interviewer. His tone was a little distant and calculated. He asked questions and he took a lot of notes. I was told that note taking is normal, but it made it feel like I was talking to a distracted doctor versus having a conversation with someone.
Interview questions [1]
Question 1
If you were Product Manager of (unnamed product), how would you improve the functionality 10x of what it is now.
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.
