I applied through an employee referral. The process took 6 weeks. I interviewed at Google (London, England) in Sep 2018
Interview
Lengthy, but great process. Good candidate experience with regular check ins. Useful interview preparation giving you every opportunity to succeed. Slick process with timely updates. Difficult to keep other opportunities with shorter processes in sync.
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.
