I applied through a recruiter. The process took 4 weeks. I interviewed at Amazon (Barcelona) in Apr 2024
Interview
La experiencia de entrevista en Amazon fue rigurosa pero profesional. El proceso incluyó una mezcla de entrevistas técnicas y de comportamiento, todas muy alineadas con los principios de liderazgo de la empresa. Las preguntas técnicas se centraron en estructuras de datos, algoritmos, diseño de sistemas y resolución de problemas, mientras que las de comportamiento buscaban evaluar cómo reaccionas ante diferentes situaciones laborales. Los entrevistadores fueron en su mayoría cordiales y claros con sus preguntas, y el proceso estuvo bien organizado desde el contacto inicial hasta las entrevistas finales. Es un reto, pero justo, y una buena oportunidad para demostrar habilidades técnicas y de pensamiento crítico.

Question 1
Cuéntame sobre una vez en que tuviste que investigar a fondo un problema complejo.
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.

Question 1
Questions were mainly hashmap, sliding window and interval related.
