I applied online. The process took 4 weeks. I interviewed at Amazon (Dallas, TX) in Mar 2015
Interview
i apply on line after three weeks i get a online coding test. it's very easy. i think every cs student can figure it out easily. after more than 2 weeks i ask for update, then i get a phone interview one week after. the interviewer is friendly to talk with. but i screw the interview at last. i stuck in the last algorithm question, and not able to give out a very clear answer.
Interview questions [1]
Question 1
On common phones each digit can be mapped to three or four letters. For instance 2 can be mapped to a, b, or c. Given a phone number represented as an array of integers, return all the possible permutations of strings for that phone number. For example [2, 3] would result in {“ad”, “ae”, “af”, “bd”, “be”, “bf”, “cd”, “ce”, “cf”}.
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.

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
