I applied through an employee referral. The process took 2 months. I interviewed at Amazon (Vancouver, BC) in Apr 2020
Interview
My interview was virtual because of COVID-19 situation. I have 4 sessions with 4 different people. They check my algorithm skills, code maintainable and structural and data structure knowledge. Last session was about System Design.
Interview questions [2]
Question 1
Each interview started with questions related to Amazon's LP(first 15 min).
Then one task to code in online editor:
1.I had simple task for DFS: Given a binary tree containing digits from 0-9 only, each root-to-leaf path could represent a number. Find the total sum of all root-to-leaf numbers.
2. Given a grouping of Amazon Objects, where an Amazon Object has a name, a unique identifier, a number of clicks, and a category, can you write a function that returns the Top N
items in each category?
3. Find all files in filesystem which size is greater then 5 mb.
4. TinyUrl system design.
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
