Hiring for college students is through their campus recruiting process. There are usually two rounds of interviews, each involving one or two people. They focus mainly on situations and how you handled them, as well as what you learned from the experience. In the second round, there is usually a technical question to test your technical knowledge and problem-solving skills.

Nothing really challenging. As long as you have a good command of your school and work experiences to draw from for the "situational" questions.

For the technical questions, you should not have problems if you have been diligent with your computer science classes and project work.
