Start with a phone interview that assesses your skills and background as well as fit for the position. Final interview is in the office usually with the manager you will be working with.

This was a very easy process because they asked very basic questions and did not delve deep into the details. In addition, they know that you are only in college so they do not grill you on any major technical questions. It was a phone screening and then if you get the opportunity to proceed, you get an in-person interview.
