Amazon Sr. Software Engineer interview questions

Six rounds of interviews: 3 are coding, 1 for design, and other two are behavior and design. Lunch buddy took me out for lunch. I enjoyed the whole process though I did not perform well in coding interviews. All interviewers are nice and willing to help you with tips when I had difficulty to come up with an optimal solution.

I was sent a link to a screen sharing platform, there would be live coding during the interview. I was to confirm first I could access it. I was told the coding could be in one of a handful of languages; Java, C++, Python, Ruby, etc. Since it has been some years since I wrote production level code, I chose Python. Probably not the best choice since I only know the basics. On the day of the interview, I received a phone from the interviewer 2 hours before the scheduled time. I was surprised and my interview routine was not shaken. I'm not sure if this was on purpose or not the interviewer claimed it was a mistake on by the person who scheduled it. After a discussion, we decided to keep the original time for the interview. I shouldn't of let this bother me but it did. The official interview started at the correct time, re-introduced ourselves and discussed how the coding would go. There also was a short summary of what the job duties were and past projects the team has worked on. The interviewer said they didn't know Python but that was ok. We completed the coding segment, then I was given time to ask questions. I asked specific questions about the organization of the projects, team members, experience of the team, things that would make a job fun or a pain. The whole interview lasted 60 minutes.
