The process took 6 weeks. I interviewed at Amazon (Seattle, WA) in Mar 2012
Interview
I got two phone interviews (They are 1 week apart from each other). They considered the fact that my background is not CS. (I'm in EE. but I have experience on system software engineer ) They asked basic questions. All questions are in typical coding interview books. I was called to on-site interview. there were 5 interviews including lunch interview. All questions are in glassdoor interview experience. but I'm not so good to explain even basic things. So rejected
Interview questions [1]
Question 1
what's the most difficult technical challenge that you faced and how did you solve it
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.

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.
