Amazon Software Development Engineer Intern interview questions

Asked some algorithm questions and questions related to object oriented design. Asked to write code to serialize a binary tree and send the code in.

Handed my resume to Amazon recruiters at my university's recruiting event and received an invite to interview with them about 2-3 weeks later, which took place on campus. The interview itself consisted of two 45-minute 1:1 interviews and were with software developers from various Amazon teams.
