I applied through a recruiter. The process took 1 week. I interviewed at Amazon (Atlanta, GA) in Aug 2013
Interview
I was contacted by a recruiter out of the blue for a local recruitment event based on my linkedin profile. All correspondence was via email - no phone calls. An online test was scheduled using interviewzen almost immediately. I wasn't contacted after the test even after repeated email followups.
Interview questions [1]
Question 1
Write a function that converts an int into its alpha-numeric equivalent represented as a null terminated string. The function should accept an int as input and return a string as output. For instance, calling the function with an int value of 324 would return a null terminated string containing "324". Ensure that your function checks for appropriate boundary conditions and edge cases. Assume you cannot use any standard libraries (for example, no itoa or sprintf).
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.
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
