Amazon Software Engineer Internship interview questions

OA process only, still waiting for VO: easy list/array manipulation problems but be careful on the time complexity, need to practice for the most optimal solution. need to be familar with Leadership Principle as well.

The interviewer was nice and friendly. For behavioral question, it was on challenges faced during a project, and how u solved it and what did u learn from it. For technical, I got a LC Hard on vertical traversal of a binary tree.
