I applied online. The process took 3 weeks. I interviewed at Amazon (Seattle, WA) in Oct 2016
Interview
I applied online on Amazon careers site and got an online assessment a few weeks later. Online Assessment consisted of a 20 minutes debugging questions (7 questions), fairly easy and 35 minutes Aptitude Test. After this round, there was a proctored round of nearly 3 hours. 90 minutes was a work simulation and 90 minutes was 3 coding questions. If you perform fairly decently, few test cases did not pass then you will get called for group assessment on-site in one of their offices. If you do your second round rather well, then you will either get offer or a very easy Skype interview where they ask behavioral questions.
Find the maximum average a person has been manager for and return a pointer to that node.
P.S: This is a graph question. BFS approach can be used to solve this.
Recruiter screen, online assessment, technical interviews, and behavioral rounds focused heavily on Amazon Leadership Principles. The process was structured, with a strong emphasis on problem-solving, coding skills, and examples demonstrating impact and ownership.
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.
