Amazon Software Engineer - Intern interview questions

The interview process included two 40 minute technical phone interviews. The questions were fairly straight forward, although as a candidate for an intern position I was surprised to be interviewed by a senior developer. Had I more experience or practice in Java, the questions might have been easier to answer.

I got a call from the recruiter about two screen interviews. They asked only coding questions, no behavioral questions at all. Time is not a big problem. There were two recruiters. Each of them asked two questions.
