Amazon Amazon Software Development Engineer Co-op interview questions

I recently interviewed for the SDE role at Amazon. The process was structured, professional, and technically challenging, just as expected from a company of this scale. Interview Process: Online Assessment (OA) – Two coding questions, primarily focused on arrays and strings. Moderate difficulty. One required optimal time complexity. Technical Round 1 – Focused on Data Structures and Algorithms (Binary Trees, HashMaps). Also included a system design mini-case (low-level). Technical Round 2 – Dive into real-world problem solving and behavioral questions (STAR method). Asked about projects and coding decisions. Bar Raiser Round – This was intense. Behavioral focus with deep dives into Amazon Leadership Principles. Also tested ownership and conflict resolution.
