Amazon Web Services Software Engineer interview questions

I had 4-5 interviews in the loop. The first one was a system design interview - 2 interviewers (asked to write classes that would make up the system). Asked if i knew common design patterns. Second, was a bar raiser interview. Third, was a leetcode graph style question with minor variation. Final was a hiring manager interview which involved using a priority queue. Not exactly leetcode questions but similar enough. Each interview involved a behavioral section with STAR method recommended.
