Amazon Software Development Engineer interview questions

Applied online to many jobs, got a referral from a current employee and that was the one I got an interview for so I think it helped. First round was an online code challenge, 2 questions in 60 minutes I believe. Passed and got an in-person interview scheduled about 2 weeks later. Company paid for travel and hotel. Interview day was a full afternoon with 4 back-to-back 50-min interviews as interviewers rotated through the conference room. Each interview started with 1-2 "behavioral" questions/discussions that took 10-15 min, and then a technical question for the last 30+ minutes. I had the option to whiteboard code or do it in an online code-sharing UI. I used a mix of both in the interviews. I was also allowed to choose the language I wanted to code in, which was nice. Turnaround was very quick - got an offer 2 days later, then about a week to finalize everything and started within a month.

Email from recruiter, online programming test and survey, phone call with recruiter, virtual onsite interview. It was a smooth process and everything was as expected with these big N company interviews
