I applied through a recruiter. The process took 3 months. I interviewed at Google (Mountain View, CA) in Jan 2018
Interview
Exactly as what others described here on glassdoor. Then, contacted by the recruiter, 1 phone interview, followed by all day multiple FTF interviews on site. Some of the interviewers are from other site and they called in remotely via video conferencing.
Interview questions [1]
Question 1
exactly as people described: design, design, design, strategy, technical
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.
