Before going to a interview there a few things you should do:
Learn as much as you can about the company. It's products and services, its profit margin, its managment, its culture, its dress code, and anything else you can think of. Do practice interviews with a career counselor, friends, and family members or white yourself in front of a mirror. Many career services centers offer workshops, mock interviews, or 1 on 1 coaching. Even making video tapes of mock interveiews. Think about how your experience in work, classes, and activites can relate to the job you're seeking. Arrive to your interview 10 minutes early.
Plan your interview attire in advance and make sure your clothing is pressed, your shoes are shined and your hair and nails are well groomed. Bring extra copies of your resume and a list of references. Speak slowly and clearly and don't be afraid to pause for a moment to collect your thoughts. Be honest don't try to cover up mistakes. instead, focus on how you learned from them. Be assertive. Remember that the interview is a way for you to learn if the job is right for you. ask the interviewer for a business card and send a thank-you note or e-mail soon as possible.
Bring copies of your resume 25 to 40 of them, depending on the size if the event. Be sure it represents your knowledge, skils, amd abilites effectively. It needs to look professional, easy to read format on a plain white piece of paper, or cream colored paper. and be free of typos. If your looking at several different career options, you may want to bring 2 or more targeted resumes with different career objectives.
A smile, a strong handshake, and a positive attitude. First impressions are important. Approach an employer, smile, and offer your hand when you introduce yourself.
A 30 second "sales pitch." Hand the recruiter a copy of your resume and be perpared to expand on it quickly. Share basic information about yourself and your career interest.
Information about your organizations which will be attending. Gather information as you would for a job interview. To maximize the brief time you have with each employer, you need to know how your skills and interest match their needs.
Energy. Career fairs require you to be on your feet moving from table to table for an hour or so. Be at your best.
