Amazon Intern - Software Engineer interview questions

Submitting application online and about a week later was asked to schedule a phone interview. The interview consisted of two different calls each about 45 minutes long with a 15 minute break between them. The two callers were both very friendly and easy to understand. They were almost entirely technical in nature. Some questions were just explaining how you would solve a problem and some were writing code. Questions included how to implement C++ set insert and access functions, how to find if two numbers in an array sum to the same number and some object oriented design questions.

Had two phone intervews back to back.
