Know the interviewer's full name, the correct pronunciation and his or her title. Be well-groomed and dress appropriately. For men, this means a dark suit and tie or sport coat and tie. For women, this means a business suit or tailored dress. Wear minimal jewelry and polished, unscuffed shoes.
Hair needs to be neat and business-like.
Don't go to the interview smelling of tobacco smoke, heavy cologne or perfume. Bring the items you will need such as a copy of your resume, list of references, samples of your work if appropriate, and a pen in case you need to complete any forms. Practice by rehearsing answers to typical questions ahead of time, experience a mock interview at the Career Development Center, watch a videotape on interviewing, or read books about successful interviewing. Never turn down an opportunity to interview. Go on many networking interviews to become at ease in interviewing situations.
