Amazon Software Engineer interview questions

The standard interview process included three hours of interview of which it was Leetcode and Low level design, another round was of amazon leadership principles, and lastly about past experiences

I first took the interview for summer intern. It was 2 hours. First hour is basic coding test like leetcode and second one was about system architecture. It wasn't so difficult, but they ask multiple questions related to the problem. also there are lots of questions about my previous work and challenges that I faced during university to make sure if I fit into the company.
