I contacted a technical recruiter in April and she sent me an invite for OA. After giving the OA, I got an email in 2-3 business days and was notified that I was selected for the final virtual on-site round, which was scheduled for 3 weeks later. I had 5 interviews in a day where I got a chance to meet 7 Amazonians. Here's a breakdown of each interview: Interview 1/2: first 15 min - ALP, followed by a coding exercise. Spent the last 5 min asking questions to the interviewer. Interview 3: First 10 min - ALP, followed by coding exercise, a few more ALP questions and last few minutes to ask questions. Interview 4: This round was entirely behavioral. I got to learn a lot about the product, the team, and future goals. Interview 5: 15 min- ALP, followed by a System Design question and spent the last few minutes asking questions to the interviewer. Overall Experience: It was a wonderful experience. The interviewers were very friendly and helpful throughout the interview. They asked follow-up questions where they needed more information. They also answered every question I asked.
