From one who was unemployed two months ago -- the interview is your chance to brag. Don't fib, though. One of my employment coaches always said, "Absolute intergrity! Always!" Having worked for many years in "Human Resources" for some of the US's biggest companies, he knew what he was talking about.

And be yourself (but wait...you're all 'Catters...maybe this isn't such hot advice).

Another thing: scope out where you're going before the interview so you don't get turned around and can arrive 15 minutes early.

When it's over, thank everyone you talked to, including the receptionist.   In writing. (Tip: try to get cards from everyone so you know who they are and where to write them.)
