I applied through a recruiter. The process took 4 weeks. I interviewed at Amazon (Bengaluru) in Apr 2021
Interview
My Amazon interview process began with an initial screening call with a recruiter to discuss my background and the role’s expectations. This was followed by an online assessment, where I solved timed coding and problem-solving challenges. Next came the technical rounds, which included in-depth coding exercises, system design discussions, and behavioral questions aligned with Amazon’s Leadership Principles. Finally, I faced the Bar Raiser round—a rigorous evaluation designed to ensure I met Amazon’s high standards, blending technical expertise with cultural fit.
Interview questions [1]
Question 1
Detect Cycle in a Linked List: Using Floyd’s Tortoise and Hare algorithm.
First round with hr screening - 2 leetcode questions then hr manager screening then the loop which consists of 4 interviews each an hour long. The 4 interview questions they asked where three medium leetcode questions. And one system design interview question about how to shadow deploy a test software to millions of users.
Interviewed for silicon team. Have only been asked about the domain specific knowledge in 1st round and system design in 2nd round and C coding in 3rd round.
The interviews were 50 mins each.
The phone screen went longer than expected, focusing heavily on implementation details. The interviewer really grilled me on my approach to a Least Recently Used (LRU) cache, asking how I'd combine a hashmap with a doubly linked list. I felt well-prepared since I had gone through system design examples on PracHub, which made me comfortable discussing eviction policies. The later rounds included more technical questions and behavioral interviews, but in the end, I received an offer, though I ultimately decided to decline. Overall, I’d say the process was average, with solid questions.

Question 1
Design and implement a Least Recently Used (LRU) cache supporting get(key) and put(key, value) in O(1) average time. Walk through combining a hashmap with a doubly linked list, eviction policy when capacity is exceeded, and how you'd extend it to handle thread-safe concurrent access.
