I applied through a staffing agency. The process took 2 weeks. I interviewed at Google
Interview
It was mostly straight forward. Entire process took around a week. Lots of pre-vetting prior to the actual interview. Since it is contracting position, just one in person interview with the hiring manager.
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.
