I applied through a recruiter. The process took 6 months. I interviewed at Amazon (Ciudad de Mexico) in Mar 2024
Interview
En términos generales, el proceso de entrevista consiste en una revisión inicial del currículum, seguida de tres filtros que se realizan de manera secuencial. Estas primeras tres etapas están enfocadas principalmente en evaluar habilidades blandas (soft skills). Una vez superadas, se avanza a las dos entrevistas finales, centradas en programación, las cuales son conducidas por una ingeniera de software de Amazon.

Preguntas generales de tu persona y pocas de matrices
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.

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.
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.
