I applied through an employee referral. The process took 3 weeks. I interviewed at Amazon (Bengaluru) in Jul 2022
Interview
There were 4 rounds in total. 1st round was a Online Assessment Round which was held on HackerRank platform, There were 2 DSA questions that was meant to be solved within 105 mins, After that there was a Amazon Work Style Survey that took around 10-15 mins. 2nd round was Technical Round 1. It was of 60 mins And two DSA questions were asked. 3rd round was Technical Round 2. This also comprised of two DSA questions of medium difficulty and it was of 60 mins. 4th round was a HR Interview Round.

Interview questions [1]
Question 1
One variant of Burn The Tree. Leetcode's Race Car Problem. Flatten The Tree Problem.
Surprisingly easy — I expected tougher questions, but the coding round felt more like a warm-up. The main challenge was a DSA problem about counting islands in a 2D grid, which led to a discussion on DFS versus BFS and handling large grids. Funny enough, I had revisited that exact type of question while prepping on PracHub, which made me feel more confident. The interview wrapped up with a behavioral round, and I accepted an offer, but ultimately decided to decline it for another opportunity. Overall, it was a smooth experience.

Question 1
Number of Islands — given a 2D grid of '1's (land) and '0's (water), count the number of connected islands. Walk through DFS vs BFS, and discuss how to avoid revisiting cells (in-place mutation vs visited set) and what changes if the grid is huge and must stream from disk.
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
