There are some very good suggestions posted here. I really can't add any more to it, but to encourage you to feel your competance. After your preparation, take heart in how well you know you can handle the job for which you are applying. Once you accept that you are the person for the job, you will project it to others. What does Oprah say about luck....it's when preparation meets opportunity....and you've got a handle on both aspects. Still, I can't resist in saying, Good Luck!
