I applied through college or university. The process took 2 days. I interviewed at Amazon (Vellore) in Jul 2012
Interview
It was in-campus recruitment. Initially there was an online round consisting of 20 multiple choice questions and 2 programming questions. The MCQs were mix of aptitude and technical.
17 students were shortlisted, out of which top 5 scorers advanced to interview round. The others had further technical round and one of the questions was on doubly linked list. It was an elimination round and those who passed, joined the top 5 for interview.
The interview was mostly technical (no HR interview) and there was one interviewer in each interview round. Questions were asked related to project work we have done in the past(as mentioned in resume). Besides, we had to write code (on A4 sheets) regarding trees and lots of question on time-complexity.
No. of interviews varied from student to student. I had two.
Interview questions [1]
Question 1
The question on finding time-complexity of a recursive function was the hardest.
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
