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.
First round with hr screening - 2 leetcode questions then hr manager screening then the loop which consists of 4 interviews each an hour long. The 4 interview questions they asked where three medium leetcode questions. And one system design interview question about how to shadow deploy a test software to millions of users.
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.
