Prepare a 90second "elevator pitch" that highlights all of the important accomplishments on your resume and a little bit about yourself. This is a good thing to memorize and practice in order to answer what is usually the first question in an interview- "Tell me a little about yourself." If you have this memorized and ready to immediately recall you can start the interview in a confident way. Also, do a lot of research so that you have well educated questions at the end of the interview. Be personable and friendly.
