Round 1: The interviewer is Software Eng. Manager started with a brief introduction, followed by around 20 minutes of Amazon’s Leadership Principles (LP) questions. I felt pretty good about my answers, and the interviewer responded positively, saying "good" to most of them. After that, we moved on to the coding problem. It was an easy LeetCode question where I had to use a HashMap. I managed to solve it and he asked if there's any alternative approach. I solved the alternative approach, explained time and space complexities for both approaches and completed the follow-up questions. We wrapped up with about 5 minutes to spare. Overall, I left the first round feeling confident. Round 2: He is Engineering Manager, and the round started with introductions, and the interviewer was super friendly, which helped ease my nerves. We began with LP questions, and I initially did well. However, I misunderstood one of the questions and ended up giving a different scenario. I realized my mistake, paused, and corrected myself by switching to the right example. Later for the next set of questions I didn't do as good as the round one. Next, we moved on to LLD. I misunderstood the initial question again, but through the clarifying questions I asked, the interviewer explained it further, and we eventually got on the same page. I designed the solution, and as we progressed, the interviewer added more requirements. I was able to adapt and implement the changes, finishing all the requirements in about 17-18 minutes. Before we wrapped up, I asked few questions about his work at Amazon. He explained about his project and we were already 10 min over the time by the time he completed explaining , so he said, "We’ll have a chat soon" and ended the interview. I wasn’t sure how to take that, either positive or he wants to leave as he is out of time..! but he was definitely the coolest interviewer I’ve had! Round 3: This was with a senior SDE, and he started by asking me to explain about the technologies I know. We then moved to an LP scenario where I had to describe a situation where I made a decision and saw it through in a project. I shared a story about how I sticked to a decision and made my manager and co-workers agree to implement it in the project. The interviewer asked very deep follow-up questions about how I executed it and if there were any other ways to do it. I offered alternatives and also explained how I would improve the solution now by adding new tech to enhance latency, which seemed to satisfy him.
