First off, it’s important to be clean and fresh overall. Make sure there are no visible stains or tears on your clothing, and that you’ve showered before the interview. Make sure your hair is well-brushed and in place. For an interview at a health facility, one of the best strategies is to go for business or business casual. For men, this can mean a full three-piece suit, or at the very least, a crisp button-up and tie. For women, this can mean a pant or skirt suit, or a dress with a conservative neck and hemline. Your hem should be no shorter than knee-length. Go for neutral colors like black, grey, or navy. Avoid flashy colors or patterns. For jewelry, go for studs or small hoops with a small, non-distracting gem, or a tasteful chain and a small pendant.
