Amazon Software Development Engineer SDE I interview questions

Round 2 (December 16, 2024, 11 AM — 12 PM) This was another DSA round, where I was given a problem based on maps (hash tables). It was an easy-level question and I solved it without much trouble. After clearing this, I received a call scheduling my third round on the same day at 2 PM. Round 3 (December 16, 2024, 2 PM — 3 PM) — System Design The system design question was: Design a bookstore system where multiple books exist, and you need to return the count of a particular word(fictional character) appearing in a specific book. I had to define the classes, objects, and methods I would use. I structured my solution well, and the interviewer seemed impressed. After this, we discussed my projects, where I explained my contributions, problem-solving approach, and impact. This round went smoothly, and I was soon notified about the final round. Round 4 (December 17, 2024, 5 PM — 6 PM) This was a mixed technical + deep-dive round. The interviewer first asked about my work at my company, diving deep into the tech stack, architecture, and design choices I had worked on. After 40 minutes of discussion, he said there was still time left, so we moved on to a DSA problem. The question was a medium-level Sliding Window problem. I solved it, and that concluded my interview process.
