I applied online. The process took 5 weeks. I interviewed at Amazon (San Francisco, CA) in Jun 2015
Interview
An engineer from the team called me for an phone interview. He very quickly asked a few questions about my resume and then he opened gave me a collabedit link and asked a coding question. It was a rather easy one. Engineer was very friendly and helpful. After I solved the question, he asked a lot of general questions about multithreading and object oriented design.

Question 1
he gave me two sentences and wanted me to return a list of words that exists in one sentence but not on the other one. for example s1 = "I am happy" s2 = "I am old", you have to return ["happy", "old"]
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.

Question 1
Given an array of integers return the indices of two numbers summing to a target
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.
