Amazon Software Development Engineer (SDE) I interview questions

Online Assessment (OA) The first step was an online coding test. It included two algorithm-based problems that tested my problem-solving skills using data structures like arrays, hash maps, and graphs. There was also a work simulation section where I had to choose responses based on Amazon’s Leadership Principles. Technical Phone Screen After passing the OA, I had a virtual technical interview with an Amazon engineer. This lasted about 45 minutes and focused on a coding problem that I had to solve in a shared coding environment. The interviewer encouraged me to explain my thought process and optimize my solution. Onsite Interviews (Virtual in My Case) The final round consisted of four back-to-back interviews: Coding Interviews (2 rounds): Each round involved solving a data structures and algorithms problem, similar to LeetCode medium/hard problems. I was asked to implement my solution and optimize it while explaining my approach. System Design Interview: I had to design a scalable system for a given problem, discussing database choices, API design, and failure handling. Behavioral Interview: This focused entirely on Amazon’s Leadership Principles. The interviewer asked situational questions like "Tell me about a time when you faced a conflict in a team and how you handled it." Using the STAR (Situation, Task, Action, Result) method helped structure my answers effectively.

Very friendly, relaxed atmosphere, the interview questions were not difficult, and the interviewer also gave appropriate prompts. The interview lasted for three hours. The first one was about behavior, the second one was about code, and the third one was half and half.
