The interview process as a whole wasn't bad. The questions weren't particularly difficult, however they looked at communication cues more than anything (eye contact, fidgeting, etc.) If you want to work in the co-op department, have these skills down. If you are applying to any other area of the university, I highly recommend networking beforehand to get the position. It never hurts but at Northeastern since it is so pre-professional, you need to have your stuff together so you can show students how to network too.
