Me postulé a través de un reclutador. Acudí a una entrevista en Amazon
Entrevista
I had an in-person interview which consisted of four, one-hour, one-on-one interviews. Two of the interviewers were managers, and the other two were individual contributors. The first question was write a function to determine whether or not two binary trees were mirrors of each other. I was also asked to write a hashtable in a language of my choice, but preferably not a language that has a native hashtable. I was also asked some data modeling questions by one of the interviewers. One interviewer also asked me to implement the itoa function in C. I was also asked to write a binary search (again, in a language of my choice).

Pregunta 1
I was asked about balancing binary trees and the order of searching a balanced tree. While this is probably not a tough question for those that have studied computer science, it was for me since I hadn't heard of it before.
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.

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.

Questions were mainly hashmap, sliding window and interval related.
