Amazon Software Development Engineer III interview questions

Recruiter found me on Linkedin, given call to my phone number. Later did online test, two programs are given, one is traversal of tree edge nodes only, other is designing card game interfaces, purely about design process. Selected on online screening, moved into face to face interview, had 5 rounds.

Phone screen was easy. Flew to Seattle. The reception was not great or special. The now famous frugal feel of the place. The meeting room was small and suffocating. Most interviewers were senior. I found the interviewers less conversational. Some of them were antagonistic. We disagreed on some issues, but instead of adjusting their questions to clarify and spell out the reason for disagreement, they repeated the same comment over and over.
