Part two of the interview is a question about some recent project that the candidate worked on. For interviewing a college kid, ask him about his senior thesis or about a course he took that involved a long project he really enjoyed.
For example, sometimes I will ask, "what class did you take last semester that you liked the most? It doesn't have to be computer-related." Actually I am usually pretty happy if they choose a non-computer related course.
Sometimes you look at their schedule, and it looks like they are taking the bare minimum number of Comp Sci courses, but every elective is something related to Music. Then they will tell you that their favorite course was Object Oriented Databases. Yeah, right. I'd be happier if they admitted that they just liked music more than computers, instead of sucking up.
