Moisturize

Wear facial moisturizer — even if you're male! An interviewer will spend most of his time with you looking at your face. While your overall appearance is very important, your face is absolutely crucial. If you're going to wear makeup, it needs to be perfect, as well as appropriate. Make sure to brush your teeth, remove any dry skin and generally make sure your face looks perfect. A little lotion is actually one of the simplest steps you can take to improving your appearance before an interview.
