Asking about what projects you have done and what were the difficulties faced. Then they will tell you the job scope you will be required to work, and the work arrangements if necessary.

Two employees per interviewee, covering each other's blind spots. Relaxed attitudes, open minds, one interviewer was an NJIT alumni, so we could connect over campus experiences. Don't be afraid of saying the "wrong thing", just say cool and speak your mind. Now they have apparently have more co-op positions and fewer internships, but that is better in my opinion.
