Here are the most commonly searched roles for interview reports -
I applied through a recruiter. The process took 2 weeks. I interviewed at Amazon (Seattle, WA) in May 2018
Interview
The first step was a phone interview which lasted about one hour. Two questions. One required to think a little out of the box and explain how to solve a difficult technical problem. No coding required, just explain several approaches, even if not optimal. The second question required coding on some online editor a simple tree traversal.
The second step was an interview on site. About five hours, with a mix of technical problems and behavioral questions.
The technical questions were moderate to difficult. They were all variations of classic algorithms and data structures. I'd recommend to be well prepared especially on sorting, searching, trees, graphs, stacks and queues. It will give you the basis upon which to think and try to solve the problems themselves. One interview revolved entirely around system design. So some ad-hoc preparation is required if you're not used to deal with scalable and distributed sytems.
The behavioral portion of the interviews is much bigger than one would imagine for a developer role. This has been stressed by many on this site, and you'd better believe it. Prepare as many situations as you can recall from your experience. Try to link them to the Amazon leadership principles. It will be a mistake to try to improvise this part, because it accounts for a good 40% of the interview and the interviewers will ask you to go into quite some detail.
Interview questions [1]
Question 1
Classic behavioral questions such as situations when you made a mistake and how you handled the situation. What was the outcome of the situation. On the technical side: queues, stacks, graphs, sorting, searching, merging, binary trees.
total 5 rounds - First OA assessment, quick telephone interview with recruiter, followed by 4 back to back technical and behavioral rounds. In technical round question were around topological graph sorting, cycle detection in linked list, and LRU cache. In behavioral round, the question were based on their 16 principles.

Question 1
How do you manage the disagreement at your workplace.
I applied through an employee referral. I interviewed at Amazon
Interview
The process started with a brief 30-minute phone screening with a recruiter, focusing on my background and resume.
After that, I was invite to a technical video interview with a senior engineer. This round lasted about 60 minutes, starting with a brief introduction, followed by a live coding challenge on a shared editor, and ended with a few questions about system design basics and my past projects.

Question 1
Implement a function to find the first non-repeating character in a string and discuss its time and space complexity.
During the coding round, I was thrown a problem on edit distance that felt eerily familiar. Mid-way through, I realized it was the same question I had practiced on PracHub just a few days earlier. The interview included a system design question about the Amazon Locker service, which required me to think through various components and customer flows. The final round involved behavioral questions that focused on leadership principles. Overall, the process was challenging but fair, and I was thrilled to receive an offer that I happily accepted.

Question 1
Compute the edit distance between two strings and walk through the DP table and optimizations.
