Amazon Software Developer Engineer Internship interview questions

The single-round interview consists of two LeetCode medium-level coding questions and two behavioral questions centered around Amazon’s Leadership Principles, evaluating both your technical skills and cultural fit with the company’s core values.

During Amazon's virtual onsite for the SDE intern role, I was asked a coding question involving prefix search. Given a list of words and a prefix, I had to return all matching words. I started with a simple startswith() loop, then optimized it using a Trie. Implemented insert, prefix search, and DFS to collect all matches. Interviewer was friendly and liked the structured approach.
