I applied online. The process took 1 week. I interviewed at Amazon (Monterrey, Nuevo León) in Sept 2014
Interview
The interview was purely online. The platform streamed videos with instructions and then I was requested to write my answers inside a text box or to record a video of myself redacting the answer. This interview was a filter to assist to an special recruiting event in Guadalajara, Mexico. The process was very transparent and easy to follow. My complain is that the online platform HireVue prompted me out randomly when I was already doing the interview and I had to test three different browsers to set up the configurations of cam/microphone before starting.
Interview questions [1]
Question 1
I was requested to: 1). record a video redacting your experience as a developer and the aspect of your work where you are most passionate. 2) When would you use a LinkedList or a Hashmap to store data. 3). programming challenge 4). what would be your biggest constraint: memory or CPU when running the previous program (point 3) for millions of input lines. 5) record a video asking Amazon something you are interested for.
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.
