I applied through an employee referral. The process took 4 weeks. I interviewed at Amazon in Mar 2011
Interview
Summer SDE intern position. Totally three phone interviews. It seems that you get the third one if you can pass the first two. Questions are not difficult but you should be very careful when solving easy questions. Think about boundary conditions and error handling in your codes. I was a little bit surprised that I did not get an offer. I thought I performed OK at last interview but I received rejection mail two days later.
Interview questions [5]
Question 1
Find second largest number of the given integer array? What about finding Kth?
A log file contains records of IP addresses that have logged on to the server in one hour. Given two log files for two different hours, how can you find the IP address that have logged on in both hours? What to do if memory is limited?
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
