Amazon Software Engineer Senior interview questions

The interview was conducted by the hiring manager, using Chime (Amazon's own video call system) and lasted for ~50 min. We had several connectivity issues and at some points lost of connections from the interviewer. He spent some time talking about his role inside the company before moving into my profile or questions. During the whole interview he gave no feedback or conversational flow whatsoever. This together with the connectivity issues made the experience a bit frustrating.

This is the most disorganized interview process I've ever been part of. I've given up after 3 weeks of trying to make it work. First, their online application system is useless; your application will be quietly marked as "dismissed" without explanation and you'll never know about it. Finally a recruiter contacted me instead. They started passing me around from one recruiter to another to the point where I didn't know who my point of contact was. When they finally scheduled an interview, I logged on but the interviewer never showed up. Then they e-mailed me in the middle of the night apologizing, and re-scheduled the interview for 9am the next morning -- an e-mail which I of course didn't see until I woke up.
