"I never feel that I'm prepared and in fact, out of my fear I don't even attempt to prepare much."

Well, try preparing then. Try doing a "mock interview" with a couple of friends. Practice answers to the typical dumb interview questions ("What is your greatest strength?"). Bring along a nice looking "portfolio" folder with your resume, samples of work, that kind of thing, that way you have something to talk about and visually distract yourself from being nervous.
