Don't just go over your CV. An interview is a chance to present all of your qualities that a CV can't present.
Never be late. Plan for the unexpected.
Don't brag too much. Being humble is powerful.
Consider your answers. You shouldn't feel pressure to answer rapidly.
Dress smartly. Be smart and groomed.
Learn about the employer, interviewer, and their history.
Job Hunting Tips:
"One step at a time. Remember that your CV will not get you the job on its own. Its purpose is to get you the interview. Make sure your CV will pique the employers’ attention so that you can get the first interview - and then that is where you will get the job."
