Amazon Software Development Engineer-II interview questions

Got an a call with the recruiter after a phone call. Recruiter was very nice, the best I have ever worked with. Very honest and straightforward. We set up a technical phone interview. After the interview, we set up an onsite. The onsite was pretty standard and basically what I expected: heavy focus on behavioral and technical. I would say the split was 60-40. Questions were fairly standard and on the easy side.

Started with a recruiter call, followed by a 1-hr online test . It was not difficult if you are well versed with algorithms and can identify patterns in problems. I was then invited to interview at a hiring event, there were about 15 other candidates. The onsite event had 4 rounds of whiteboard coding, 1 scalable system design, 1 object oriented design and 2 algorithms/problem solving rounds. Each interview had many questions on amazon leadership principles so make sure you read them and also prepare your answers based off those leadership principles.
