I applied through college or university. I interviewed at Amazon (Calcutta) in Oct 2019
Interview
One online round followed by 2 face to face interview rounds. Online round consists of around 10-20 mcq and 3 coding questions of easy level. During each round of face 2 face interview, was asked about projects and 1 coding question each round of med-high difficulty.

Question 1
1. Given a two linked list containing numbers. Add them and return a linked list containing the sum of two numbers.
2. Given a binary tree, add another link to the right node of each node in same level.
Eg, Given tree containing links : 1-2, 1-3, 2-4, 3-5
Output tree containing links: 1-2, 1-3, 2-3, 4-5
3. Questions based on projects mentioned on CV.
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.

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.
