I applied online and received an online assessment that needs to be completed within 7 days. The OA takes a total of about 2.5 hours: 90 minutes for coding, consisting of two questions. The first is an algorithm coding problem, and the second is a practical debugging task, involving both frontend and backend components with API POST and DELETE calls. Once you locate the backend POST API, you can find the place to work on it, while the DELETE API calls require more detailed fixes. I ran out of time on both questions. In my opinion, the assessment seems to have been upgraded this year. The behavioral tests are not timed, so you can take a short break for water or restroom.

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
