Submitted application online and went through a phone interview with the recruiter and then onto the hiring manager for two phone calls as we weren't able to cover everything in the first one. After the the phone interviews it progressed to a in-person meeting in Mountain View where I presented a mock case study after they presented me a prompt. After the hour long presentation it progressed to 2:1 interviews with folks on the team. The case study presentation was a lot of work and time which was received well by everyone in the room and in the 2:1 interviews. Still confused as to how the feedback I received was two bullet points that were so generic coming from a company that prides itself on transparency. Could have been addressed in the phone screening portion instead going through the entire interview process and presentation.
