I applied online. I interviewed at Amazon (Gurgaon, Haryana) in Mar 2022
Interview
I appeared for Amazon SDE-I FTE(Full Time Equivalent) hiring process through my college campus, in March 2021. First, there was an Online Coding Round and it was followed by three rounds of virtual interview process.
Online Coding Round: From the Online Coding Round, about 40 candidates were shortlisted for the interview process which was held in the next week.
In the online coding round, two questions (different questions to different candidates) were asked, one a bit tricky and the other one easier. I actually ended up doing neither with complete success (:3).
In my first question, I remember I passed about 8 out of the 13 total test cases and passed only 2 out of the 9 in the other one. I thought I had no chances for qualifying through but when the shortlist was published, I ended up being quite high up in the list. I was surprised but later what I learned was, the developers who make those questions, actually go through your code thoroughly and find out whether you used the correct logic (or at least close to it) or not.
Interview questions [1]
Question 1
Given a string S of distinct character of size N and their corresponding frequency f[ ] i.e. character S[i] has f[i] frequency. Your task is to build the Huffman tree print all the huffman codes in preorder traversal of the tree.
Note: While merging if two nodes have the same value, then the node which occurs at first will be taken on the left of Binary Tree and the other one to the right, otherwise Node with less value will be taken on the left of the subtree and other one to the right.
I received an Online Assessment (OA) invitation from Amazon. The assessment consisted of two coding questions of medium to hard difficulty, focusing on data structures, algorithms, and problem-solving skills. The questions required efficient solutions with optimized time and space complexity. After the OA, shortlisted candidates typically proceed to one or more technical interview rounds covering coding, system design, and behavioral questions based on Amazon's Leadership Principles.
Applied online via career site, received OA link within 2 days and cleared it, Round 1- DSA, Round-2 DSA, Round 3- System Design, Round 4- Mixed Technical Discussion and Behavioral.

I applied through university. I interviewed at Amazon (Patiala) in Jun 2026
Interview
Amazing process, was asked 2 dsa questions then hashmap internals and then basic introduction in dsa question i was given hints too, ovrall a great experience, will recommend everyone in the house
