I applied through an employee referral. The process took 6 months. I interviewed at Google in Apr 2020
Interview
The interviewer was direct and thorough. While many complain of Google's interview process I experienced this first interview as an opportunity to show of PM skills and thinking. They put emphasis on YOU identifying what kind of answer they are looking for (design, metrics, strategy) so listen closely and ask follow ups.
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.
