What is appropriate body language in an interview?

To ensure your body language signals your confidence, sit up straight with your shoulders back. Avoid crossing your legs and don't adopt a casual pose -- even if your construction interviewer does. Even if you're nervous, try not to fidget. Don't play with your jewelry, twirl your hair or cross your arms, and try to maintain eye contact with the construction interviewer. If staring straight into the construction interviewer's eyes makes you uncomfortable, look at the bridge of his or her nose instead -- it looks like you're still making eye contact, but might be less distracting.
