Deep breathing is the best thing I can think of, and trying not to over analyze it too much. When you think too much, that is when it gets all clogged up in our head, as I am sure you know.
And practice, practice, practice, blah, blah, blah. I know you don't want to hear that, but that is the BEST way to prepare yourself. Prepare questions you think you are likely to be asked. Prepare your responses and then go over it and over it again and again and again.
I had to testify in court once and I was SO nervous, but instead of dramatizing it and treating it like it was a huge deal, I just wrote everything out that I thought I could possibly be asked and I studied it for a week. And when I got on the stand, I kicked ass. I wasn't nervous because I knew I had it in the bag. It was all routine and automatic.
Sure, there is a chance you might get stumped with a question but there isn't much you can do about that. This is you showing them who you really are, and that means showing them how well you think on your feet. And the best way to think quickly on your feet is to have a confident, relaxed attitude and don't take it too seriously. So practice that attitude too. Good luck!

I agree with lilygirls suggestions. Sometimes for me I think if the motto "fake it till you make it". It is something a preceptor of mine used to say to me when I first started my nursing career. She meant like if you are going in and starting an IV or a shot - fake some confidence if not for you but for the audience (patient). It works! Inot only needed confidence to put my patient at ease but a little rubbed off on me too.

Build yourself up before the interview - your the best, you're going rock it. Psych yourself up. Visualize yourself aceing it. You can do this - you've got it! Please let us know how it goes

I spoke in front of over 300 people this past weekend. They handed me a microphone which I did not even know how to use. I did not practice using it. Freak out time, right? No!

I focused on one person and spoke to them the entire time. I looked over people's heads but not at them per say. And I felt completely calm the entire time.

Visualize success and doing well. I did go over my material so I knew what I was going to say.

If you can keep your hands from view, you can tap on the sides of your fingernails. These are actually meridian points for releasing built up tension. You can also curl or uncurl your toes as a way to foucs on something else. I hope that makes sense.

Good luck! Like Lily said - KICK ASS-LOL!!!!!

This one is hard for me because I am fine once I'm on stage or already in the interview, etc but it's the build-up beforehand that KILLS me! I have take a shot before speech class in college before! lol

Do you take Ativan or anything? Can you take one beforehand and still perform well?

It is true what the others have said, practice does make perfect. It's the only thing you can control. Good luck!!!!

Well the interview that I did for my class well excellent, mostly cause I was already prepared cause we had to write out our responses for the Q's they may ask us. They chose 5 from a list of 10. I started getting nervous several times, but calmed myself down lol The only critique she gave me was to have a firmer handshake next time which is odd cause I normally do. The one I'm really worried about is my competition because it WILL be more like an actual interview where it could be any Q and it won't be someone that I know like this one. I remember last time they did this they asked me if I could pick any actress to portray me in my life who would it be and why? And I said Drew Barrymore, but I couldn't really think of an actual reason because I don't care much for celebrities. I hate random Q's like that. Why couldn't they have asked me what flavor of ice cream I would be lol

@ledward I don't take any kind of medications for anxiety

YAY!! I am glad to hear things went so well. Take that confidence and the next time you have to do something similar remember how good it felt accomplishing this. I hope you are doing something fun tonight to celebrate!
