I applied online. The process took 4 months. I interviewed at Google (Mountain View, CA) in Jan 2019
Interview
Several rounds of interviews with product managers and engineers. Asked some basic computer science algorithm questions and more open-ended questions about problem solving. Overall, it was a good experience but a little intimidating.
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.
