I applied online. I interviewed at Amazon (New York, NY) in Jun 2025
Interview
1 Technical assessment and 3 Round Loop
Round 1:
LP round
Round 2:
1 medium and 1 hard
Round 3:
Design LRU cache and LP
First two rounds went well, though I couldn't fully answer the hard question, interviewer helped me a lot , third round interviewer was little off, after 30 minutes he asked me why can't I evict from the front of DLL and insert from the front.
I would rate myself 7/10. I could have done better.
Interview questions [1]
Question 1
Top K elements(heap) and median of two data streams(heap)
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.
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.
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.
Interview questions [1]
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.
