The process took 2 days. I interviewed at Amazon (Seattle, WA) in Apr 2011
Interview
Two phone interviews, each an hour long and followed by an assignment that I have to submit before midnight.
The difficult level is similar in both interviews, I was asked about my background, some specific questions about past project. Then questions about data structure, system design, how to improve performance of a large system. Two interviewers were from different departments, and they introduced themselves as well as their current projects.
In the end of each interview, they asked me to solve a BST problem, we discuss the solution first, then he asked me to write the code of that solution(even though it may not be the best solution) and email them after the phone interview.
I applied online. I interviewed at Amazon (Sydney)
Interview
I can't comment much. I submitted an application for the software engineer position, and not even a minute later, I received an auto rejection email from Amazon (never received an online assessment).
2 behavioral 2 coding not very difficult. Behavioral is tell me about a time you took responsibility beyond your role and biggest accomplishment. The process is exactly the guideline they posted for interview.
Interview questions [1]
Question 1
tell me about a time you took responsibility beyond your role
It was a 2-3 round process, depending on how your interview went, with increasingly hard DSA questions followed by some HR and behavioural questions. First round was mostly easy and medium leetcode, followed by medium and hard questions in the second round and above on more complex topics.
