I applied through an employee referral. The process took 3 months. I interviewed at Google (Mountain View, CA)
Interview
The interview involved a phone screen with a PM, and then an onsite round consisting of multiple interviews over the course of a full day in Mountain View. The onsite interview was a mix of different things, while each onsite focused on 1 or 2 questions specifically. There was a technical interview, and then several with PMs of varying levels. Overall, the questions were fun problems to think through and solve. I actually had fun in the process. I declined only because I decided to go with another offer. The interviewers were all really friendly and helpful.
Interview questions [1]
Question 1
Most everything I was asked is available publicly. No surprises here. Google sends out an interview prep guide (what to expect). Read it well.
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.
