Recruiter screen, followed by an online coding assessment and then a technical phone interview. The final round was a virtual onsite loop with multiple interviews covering data structures, system design, debugging, and Amazon Leadership Principles. The technical questions were practical but time-constrained, and the behavioural questions required specific examples using the STAR format.

Question 1
Design a scalable URL shortening service and explain how you would handle high read traffic, collisions, database schema, expiration, and basic monitoring.
I applied online. The process took 1 week. I interviewed at Amazon (Monterrey, Nuevo León) in Sep 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.

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.
That moment when the interviewer asked about finding indices in an array for a target sum was wild — I had just tackled something identical while prepping on PracHub. The interview included a technical round with another question about designing an in-memory LRU cache and a behavioral question about meeting tight deadlines. After a smooth discussion, I was told I'd received an offer, which I happily accepted. Overall, the process felt pretty straightforward and not overly challenging.

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.
