I applied through a recruiter. The process took 3 days. I interviewed at Amazon (Seattle, WA) in Apr 2013
Interview
Phone interview:
Questions on basic data structures and algorithms. Search and sort. Basic time complexity. Hardest data structure I had to work with was a LinkedList. If you know your stuff you can write code to solve all this on-the-spot. Interviewer was cool. Suggest practicing on Project Euler.
Interview questions [1]
Question 1
Pull a random integer from the range 1, ..., N. Shuffle. Find missing integer, without re-sorting. Solution is to used closed-form sum of first N integers.
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
