Me postulé a través de un reclutador. El proceso tomó más de 1 semana. Acudí a una entrevista en Amazon en sept 2014
Entrevista
The recruiter connect me a week ago, mentioning that there's event going hosted by Amazon’s Women in Engineering group, and they wanna get in touch with me. I had a phone call with the recruiter 2 weeks ago, and schedule the first tech phone interview today. It was a nice talk with the interviewer, I was nervous, but he still nicely giving me lots of hints and advice.

Pregunta 1
What is HashTable? How does it work in the backend perspective? What to do if the collision happened? Whats the time complexity of inserting? deleting? seaching? What's the time complexity for the worse case?
Online coding interview:
Given an array of integers. Find the largest increasing sub sequence of integers in the array.
// 10, 3, 7, 9, 0, 15
// return index 1&3
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.
