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.

Question 1
Valid Parentheses: Given a string having some brackets, determine if the input string is valid.

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
