I applied online. The process took 1+ week. I interviewed at Amazon
Interview
Was part of the final interview process. 5 interviewers, 4 technical interviews and one behavioral. 45-50 minutes per person. On the technical side was asked about prior experience as a "wram" up question then an algorithm. They covered all the standard data structures: Navigation in the binary tree, linked list, search in the graph, system design based on the hash table. Some of the guys seemed very relaxed and the process was sort of working session with a collegue and some of them were a bit distant, and it was a bit hard to read-up anything from them. I got a bit intimidated when I made couple of mistakes but overall process was ok. I didn't receive an offer.

Question 1
System design of the complete online company. Didn't know how technical I should go, High level or go to specifics. I didn't read off the interviewer where to go - he just said "go ahead and just design away"
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.
