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.
I applied online. I interviewed at Amazon (Seattle, WA)
Interview
Applied for an interview online, got a response via email within a couple days asking me to come down for an interview in Seattle (no phone screening interview). Amazon was very generous in paying for my flight, hotel, food, and transportation within the city.
The actual interview was an all day programming task in which you solved a problem in a group (no whiteboard coding). I found this to be a really enjoyable process and within only an hour or so of being at Amazon I felt right at home programming my solution to the problem.
This group interview process seems to be a real winner to me, as it felt a lot more natural to actually get to write code on a computer (multiple choices of programming languages and IDEs) and have access to the internet and teammates for help. I feel lucky I managed to get this type of interview - I had a very positive experience.

Question 1
N/A (unable to discuss the problem we were tasked with solving).
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
