I applied through an employee referral. The process took 4 weeks. I interviewed at Amazon in Feb 2016
Interview
There were two rounds. First round was an online debugging challenge. Questions were fairly straight forward and easy. They were at maximum one line edits. I got a call back after 3-4 days. I scheduled a phone interview one week later. The phone interview lasted 45 min to 1 hour long. There were three questions. One was on data structures and two were coding challenges. I had a type in a shared screen between You and the interviewer. The interview went pretty well. I got a reject after two weeks!

Question 1
1) Priority queues and how you implement it.
2 a) Stacks
2 b) Tree Traversal
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.
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.
