I applied online. The process took 5 days. I interviewed at Amazon (Bengaluru) in Sep 2025
Interview
The interview began with mutual introductions and quickly transitioned into technical topics. I was asked to explain Trees vs. Graphs and their differences. Then came two DSA problems: one on greedy scheduling (N meeting rooms + merging overlapping intervals) and another on string validation (checking for repeated words). I discussed time and space complexities for both problems. The session was interactive, with follow-up questions and a focus on problem-solving. I had only 1.5 days to prepare after a short-notice phone call, so I prioritized DSA and showed less interest in theoretical concepts. Although I wasn’t selected, the experience was fast-paced and engaging, and it helped sharpen my technical thinking under pressure.
Interview questions [1]
Question 1
Can you solve the N meeting rooms problem using a greedy approach and explain how it relates to merging overlapping intervals?
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
