I had 2 phone interviews with Amazon. I was invited to in-person interview after the first one that lasted about 2 hours. Couldn't go to Seattle at that time, so I declined. Recently, I had interviewed over the phone/online coding again. Haven't heard back yet, perhaps it's not been long enough. I feel their phone and online interview is a fair game for entry level position, consisting mostly of testing of general knowledge of data structures and algorithms. Trees, hash tables, list, algorithms used on them. I felt the interviews were testing knowledge of this subject matter mostly and questions were how to optimize/improve the algorithm also. Nothing too tricky or unusual. They didn't care which language one would use either.

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.
