Amazon Software Engineer Internship interview questions

Many of us from my college who applied were invited to the local office to take an assessment. There were three parts to the assessment: a set of brain teaser puzzle problems, a behavioral survey, and a technical section with 2 programming problems. Each section had a specified amount of time given to complete it. After this, I was contacted to go to the next round, which was a phone interview. The phone interview consisted of speaking with an Amazon SDE and coding via a shared text editor.
