I applied through college or university. The process took 4 weeks. I interviewed at Amazon (Atlanta, GA) in Oct 2013
Interview
Got in contact through college career fair. Had a 45min on-campus interview 3 weeks later. The interviewer was very friendly, he gave helpful hints on how to solve the coding problems. He walked me through my code and pointed out where needs improvements.
Some problems he asked were:
Given an integer array, find any integer that occurs more than once.
Given a binary tree, test whether it is a BST.
Given two random nodes in a tree, not necessarily a BST, find their common parent.
They really focus on memory usage and time complexity of your algorithm/data structure.
Interview questions [1]
Question 1
Given any binary tree, write an method to test whether it is a Binary Search 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 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
