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.
I applied through a recruiter. The process took 2 weeks. I interviewed at Amazon (Seattle, WA) in Mar 2014
Interview
I received an email invitation to do an online coding screen. I did the screen which was very easy and they immediately invited me onsite; flown out to Seattle where I was put up in a nice hotel. I actually had a moment where I was afraid I made a mistake while sitting in the lobby waiting for my grilling, based on the amazing number of people there for orientation. I really did not like the idea of working for a company that treats their employees like a number, but I obviously forged on. I went in for my interviews and I was in over my head. I didn't really feel the questions were very fair, and I don't think my inability to answer some of them is indicative of my capabilities. I am probably a bit bitter about the whole thing, but I have since found out (from several former employees) that Amazon really overworks and burns out their employees. I unsurprisingly did not get an offer. In hindsight and after speaking with former Amazon employees, I think it was for the best.
Interview questions [1]
Question 1
Design an algorithm for finding possible meeting times between X number of people given each of those people's current schedules.
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.
