Amazon Software Development Engineer Intern interview questions

One round through Amazon Chime, asked me to introduce myself and then asked two behavioral questions with follow ups and one technical question (coding). Lasted one hour and allowed for follow up questions at the end.

Initial was 2 timed coding questions online Final was some behavioral questions followed by 2 timed coding questions with a current engineer, online. The questions were binary tree traversal, and fairly simple (class definition, recursive sum).
