Amazon Software Development Engineer SDE interview questions

The interview began with mutual introductions and quickly transitioned into technical topics. I was asked to explain Trees vs. Graphs and their differences. Then came two DSA problems: one on greedy scheduling (N meeting rooms + merging overlapping intervals) and another on string validation (checking for repeated words). I discussed time and space complexities for both problems. The session was interactive, with follow-up questions and a focus on problem-solving. I had only 1.5 days to prepare after a short-notice phone call, so I prioritized DSA and showed less interest in theoretical concepts. Although I wasn’t selected, the experience was fast-paced and engaging, and it helped sharpen my technical thinking under pressure.

3 rounds 1. DSA and Problem Solving (may be Leadership principles) 2. DSA and Problem Solving (may be Leadership principles) 3. Was going to be Leadership Principles based but not sure as I haven't got any updates on it after round 2.
