Me postulé en línea. El proceso tomó 1 día. Acudí a una entrevista en Amazon (Miami, FL) en abr 2014
Entrevista
I was contacted to do an initial interview. The interview process was all done online, on a 3rd party website where I had to solve three problems. They asked three questions in regards to manipulating data structures. I was required to solve the problems in the most optimal manner, as well as provide a reasoning on why I solved it the way I did, as well as explain in detail the time complexity.

Pregunta 1
Explain in derail the time complexity of all solutions.
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.
