I'm a first year student in the program so I might be able to give a few pointers. If I remember correctly, the interview day consisted of a tour of the facilities (library, caf, etc), a one on one interview with a professor (dont worry, they are all very nice!), and an essay to get a general sense if you know how to write. You cant prep for the essay, it's about something random. Be prepared for the usual questions...such as why PT, why NYIT, and how things in your past/present have prepared you for a rigorous graduate program. Just be honest and real! Good luck!
