I agree =D

One thing I've found useful in interviews is to act as comfortable and YOU as possible.

Smile! That's a big one =)
Take time to think if you need it. Often when we get nervous time "speed up"... you have more time than you might think.

Act confident even if you don't feel it. They called you for an interview - that's the first step and that's GREAT!

GOOD LUCK!!!!
