I applied online and got online assessment. After the online assessment, I got a onsite interview. This is a 4-round interview, each one is about 45 minutes. You'll have 5-min break between 2 rounds. Most of them are technical questions, especially algorithms and data structure problems. Have some behavior questions during every round.
Interview questions [1]
Question 1
Valid Parentheses: Given a string having some brackets, determine if the input string is valid.
Design how to recover a binary tree
OOP questions and multi-thread problems
Given a set of candidate numbers and a target number, determine whether there's a combination in C where the candidate numbers sums to the target number or not.
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

Interview
Recruiter reached out and set up an onsite loop after the initial steps. Four back to back rounds in one day. Two coding heavy rounds run by senior engineers, one round with the hiring manager, and one behavioral round with a bar raiser. Mix of leadership principles and data structures throughout. Heard back within a week.

Question 1
Standard BFS grid problem. Given a grid, find the time for all cells to reach a target state where the spread happens one layer at a time.
How did you answer: Clarified the constraints, walked through the approach, then coded a clean BFS from all starting points at once. Tracked the number of layers until everything was covered.
