Applied through referral. Contacted by recruiter(s) who set up a phone screen. Phone screen interviewer called a day before scheduled date, due to some screw-up on their part. Luckily I was available at the time and took the phone screen. Phone screen question was multi-part, medium difficulty (Leetcode level). After passing the phone screen, I was invited to an onsite at their Mountain View/Sunnyvale campus. Onsite consists of five 1-hour sessions, and an hour for lunch. The sessions include two coding sessions, one system design session, one technical communications session where you are to explain your past project(s), and a session with a host manager with behavioral type questions. All my interviewers have been with the company less than 3 years, which is probably not surprising given the industry. I got the rejection notice a week after the onsite, reason being performance on the coding and system design sessions. The coding and system design questions were not particularly difficult. Probably because of that, they expect you to come up with the optimal solution without many hints.
