Online Assessment (OA)
The first step was an online coding test. It included two algorithm-based problems that tested my problem-solving skills using data structures like arrays, hash maps, and graphs. There was also a work simulation section where I had to choose responses based on Amazon’s Leadership Principles.
Technical Phone Screen
After passing the OA, I had a virtual technical interview with an Amazon engineer. This lasted about 45 minutes and focused on a coding problem that I had to solve in a shared coding environment. The interviewer encouraged me to explain my thought process and optimize my solution.
Onsite Interviews (Virtual in My Case)
The final round consisted of four back-to-back interviews:
Coding Interviews (2 rounds): Each round involved solving a data structures and algorithms problem, similar to LeetCode medium/hard problems. I was asked to implement my solution and optimize it while explaining my approach.
System Design Interview: I had to design a scalable system for a given problem, discussing database choices, API design, and failure handling.
Behavioral Interview: This focused entirely on Amazon’s Leadership Principles. The interviewer asked situational questions like "Tell me about a time when you faced a conflict in a team and how you handled it." Using the STAR (Situation, Task, Action, Result) method helped structure my answers effectively.
Interview questions [1]
Question 1
One of the challenging questions they asked me was about optimizing a meeting room scheduling system. The problem was similar to a "Merge Intervals" type of question.
Problem Statement:
"You are given an array of meeting time intervals where intervals[i] = [start_i, end_i]. Determine if a person can attend all meetings without any overlap."
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.

Question 1
Number of Islands (LC 200 - Medium): You are heavily advised to know how to traverse connected components using a 2D grid.
Interview involved one screening OA and one final day, 3 back to back interviews, one technical, one behavioral and one mix. Focused on leader ship principles and DSA and algo
