I applied online. The process took 4 months. I interviewed at Amazon in Jan 2015
Interview
Applied online, was reached out to by a recruiter a couple of months later. Took an online test for basic coding two weeks after initial contact, passed that and moved on to technical interview. Had the technical interview about a month later. Got the no offer email a couple of days after that. Didn't answer anything incorrectly, some minor mistakes and generally didn't think I came across as confident in myself. Interviewer was a bit terse, which didn't help.
Interview questions [1]
Question 1
Write a function to check whether a binary tree was a binary search tree. My first function only handled trees with integer values and he asked me to run through the function with a tree of double/float values. I should have asked clarifying questions before I started coding.
Design a library (write out all of the classes, etc...), this was an OO question. Missed a few abstractions, basic structure was alright though.
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.

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.
