I applied online. The process took 4 weeks. I interviewed at Amazon (New York, NY) in Dec 2019
Interview
After applying on the Amazon jobs website, I was approached via email by an Amazon recruiter. They set up an online assessment for me, which were two coding questions in 90 min as well as 15 min survey asking you to explain your thinking for the coding questions, and a survey with personality questions (strongly agree, agree, disagree, strongly disagree).
Interview questions [1]
Question 1
A technical coding question included a question about binary trees and the various traversals (In-order, pre-order and post-order). If given the In-order (L, M, R) and Post-order (L, R, M), can you return the original tree? (M for mid instead of root because it starts with R). The two inputs are arrays of integers, the values at each node of the binary tree.
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 June 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.

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
