Was a fair interview process until the final round. Applied with referrals from current APM and YouTube SWE. First round was a phone screen for 45 minutes, straightforward. They had me complete an "essay" for product design--supposed to be done in 2 hours, but the context of the assignment required obviously more than that. They scheduled my onsite interviews (3 in total), but the night before, I receive an email that one of my interviews was canceled and would be rescheduled at a later date (it wasn't). I didn't interview on the main campus, but at a different Sunnyvale campus. One of my interviews was virtual with a SWE from YouTube, the second with a current PM. It seemed brief and unenthusiastic. Received rejection a week or two later, with no feedback from recruiter. Frustrating because it's unsure if my chances would've been better with my third interview.
