I applied online. The process took 4 weeks. I interviewed at Amazon (Seattle, WA)
Interview
Applied online and was contacted three months later by email with a link to a timed programming assessment. There were three problems to complete in 90 minutes. After completing the assessment, I was contacted again by email with an invitation to an onsite interview in Seattle. The onsite interview was completely technical with 4 interviewers, 40 minutes each.
Interview questions [1]
Question 1
Technical questions were all as expected, I had to write code to perform certain operations like find the nth fibonacci number, the largest product of any three numbers in a list, etc. After writing each solution I was asked to analyze the time complexity and improve my solution.
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.
Recruiter reaches out after applying through Amazon careers, no referral. Had an initial OA, then after a month had four rounds in two days - three coding one system design. Each round had 30 min behavioral and 30 min coding.

Question 1
Questions were mainly hashmap, sliding window and interval related.
