There was a coding assessment online with two questions. First question was relatively simple and took ~10 minutes to fully complete. Second question was more complicated, but still only took ~30 minutes. Was invited for an on-site interview after the coding assessment. The on-site interview consisted of 5 rounds and a lunch break (probably a personality test). Most interview rounds consisted of behavioral questions followed by a single technical question. It was unclear to me whether more questions would follow had I solved the questions faster, as the interviewers did not say much in response to "thinking out loud" unless you were asking a clarification question. The technical questions were similar to ones you would find on HackerRank or leetcode -- I suspect that leetcode actually has the vast majority of the problems stored somewhere if you pay to play. The interviewers did not give any indication as to whether or not you had solved the problem correctly, and would only ask questions at the end about potential optimizations, or time / space complexity. There was also a pretty open ended system design question which required coming up with relevant database tables. Questions on actual implementation were pretty light, and some hand-waving was seemingly allowed. I personally thought I did rather well on the interview questions, especially the technical ones. I ended up being ghosted by the Amazon recruiters after this process, to which I must assume means I did not get the job, but nobody ever bothered to tell me despite several attempts to follow up. My interviewers were largely courteous, enthusiastic, and patient people and I appreciate having the opportunity to interface with them. I would have considered this a highly positive learning experience otherwise.
