I applied in-person. The process took 1 day. I interviewed at Amazon (Seattle, WA) in Sep 2010
Interview
It was an in person interview with one of the direct members of the hiring team. It asked a question on algorithm to find the shortest prefix string. We went between brute-force solution to the optimal. Follow up questions were related to scaling, which points to the need to cache the right branches and sharding on disk. Finally, the interviewer talked about the team itself, and was really responsive to questions.

Question 1

It started with an OA, and then after a few weeks, I got invited to four rounds of interviews: technical and behavioral at 3 of the 4, and behavioral only at one.
I applied online. I interviewed at Amazon (Calgary, AB) in Jun 2026
Interview
Online Assessment is the first step in the process. I didn’t have an HR phone screening and went straight to the OA after applying. It was sent to me about a week after I submitted my application.
Interview questions [1]
Question 1
The first question is LeetCode style algorithms question, and the second question gives a full stack repo (choice of Java, NodeJS, or Django) and asks to solve a backend issue which is causing a bug in the frontend. Unit tests must pass to pass the second question. You can run both backend/frontend indivdually or together
