Appearance is always a big thing in a job interview. When you get interviewed, make sure you ALWAYS look nice, dont just slop down some tennis shoes, red shorts, and a grey shirt... Try wearing a blouse or a skirt with a red shirt, and makeup ( For women, of course!) and wear a suit, and some special shoes, and make sure you're groomed nicley( for men)... This may seem a little odd to you, but how many times have you judged somebody on what they wear--" Oh he was just wearing a ol' pair of tennis shoes and regular clothes" When meeting somebody important, make sure you give yourself the once-over before you leave the house.
