After OA, I first scheduled an interview with HR, but she didn't show up and didn't reply email at all. At the same time, I already had an interview booked with the hiring manager. HM didn't turn on camera. Questions he asked seemed randomly pulled from a list without much focus on my own experience. Looks like he didn't care what I answered either.

Standard Amazon behavioral interview with 2 prior rounds before the 5 hour loop interview. I was able to split my loop interview over 2 days. The team forcefully downgrade offers to L5 from L6 after interviews
