How do I best prepare for my school's career fair?

my school's career fair is on nov 16th and i am trying to be as best prepared as possible. i've been working at cvs for a little over 3 years and have no intention of residency or post graduate training. on the day of the fair there will be an optional interview portion for 6th year students. i believe this is an excellent opportunity for me to try to lock down some type of full time position right then and there i've looked at the current list of employers that will be attending the fair.... How do I best prepare for my school's career fair?
