You got the call! The interview is scheduled. Now what?
Sometimes when you fill out an application, the company could interview you on the spot. This article focuses on when you have a day or two before the interview.
If you have time before the interview, make a practice run to the location at the time that you would be going to work. This helps you with two things:
Once you see what others wear, you can decide what to wear. No time to make a practice run? Ask the person that schedules your interview about the company dress code. The best bet is be neutral. Nothing too extreme. No jeans, shorts, bare midriffs, flip-flops, or sneakers. Nothing too low-cut or too short. Ask yourself, "Would my grandmother approve of this outfit?" 
Guys – black, blue, or khaki slacks, belt, polo shirt, or long-sleeve, button-up shirt with tie, and tucked in. Dress shoes.  Everything clean and pressed.
Girls – skirt or pants with a top, or a dress, and comfortable shoes. Remember: nothing too revealing. Easy on the jewelry, hair, and nails.
Determine how you will walk, stand, or sit when you first meet the person who interviews you.
Learn the appropriate way to shake hands.
Practice answers to standard interview questions.
Research the company – size, locations, history, products, and competitors.
Let your references know you have an interview.
Have a notebook with extra copies of your resume, the information you gathered about the company, and questions that you want to ask the interviewer.
Follow these tips and it will be like having an ace up your sleeve. Who knows, you may be offered a job on the spot! As a final step, remember to send a "thank you" letter to the interviewer.
