I applied online. The process took 3 months. I interviewed at Amazon (London, England)
Interview
Phone interview - fairly standard software dev and HR questions.
Face to face interviews - 4 interviews with 2 interviewers in each and 1 "bar-raiser" interview. 45 mins each. Very little break in between and ran over my lunch break, so didn't have any lunch. Also, didn't get to see any of the office and was abruptly shown to the door after the last interview as the HR person wasn't there. Didn't have a good impression of the company from the interview process.
Interview questions [1]
Question 1
Write a function to validate a binary search tree.
Assume there are supporting classes and functions already.
Try to prioritise speed - don't worry too much about memory.
- What other test cases would you use?
- How to do it without recursion?
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
