I applied through a recruiter. The process took 2 weeks. I interviewed at Amazon (Hyderâbâd) in Dec 2012
Interview
Recruiter had short-listed my profile from one of the job portals and contacted me to schedule an online coding test on interviewstreet.
The questions were:
1. Find all prime numbers before the given number n.
2. Find the kth largest number in a BST
3. Find the transpose of a given matrix.
4. Given a directory with several different files. Find the student with max avearge number.
one more, which I dont remember.
Time given was 2 hrs.
After going through, had the first telephonic round.
Questions asked were:
1. Find the missing card in a deck. The cards are passed as a stream of input.
2. Find the median of 2 sorted arrays.
3. Construct a tree from the post and preorder traversals. [Asked to mail the code for the same within 15-20 mins.]
I messed up and hence within a week got a regret mail, but the experience helped me in identifying my areas of improvement.
Interview questions [1]
Question 1
Find the missing card:
I gave an O(n) space approach using hashtables, but he wanted a much better optimized solution, after some thinking thought of using only required bits or using the cards as an A.P., however these thoughts came after the interview.
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
I applied online. I interviewed at Amazon (Santa Clara, CA) in Jun 2026
Interview
Recruiter reached out and set up an onsite loop after the initial steps. Four back to back rounds in one day. Two coding heavy rounds run by senior engineers, one round with the hiring manager, and one behavioral round with a bar raiser. Mix of leadership principles and data structures throughout. Heard back within a week.

Question 1
Standard BFS grid problem. Given a grid, find the time for all cells to reach a target state where the spread happens one layer at a time.
How did you answer: Clarified the constraints, walked through the approach, then coded a clean BFS from all starting points at once. Tracked the number of layers until everything was covered.
