What after IT helpdesk?

Hey so couple of days ago I got my first interview in 10 months of consistant applying in that brutal market for an "IT Helpdesk Specialist" position and I passed the HR interview and I'll be taking the technical interview in a couple of days. I just want to know what to expect in that interview? I already studied MCSA & CCNA and know some stuff about IT in general so am wondering what are the common technical questions asked for that position?
