Be confident, yet relaxed. Remember to make eye contact and have good posture. If you have a briefcase, purse or jacket, find an appropriate place to put them, not on your lap. Don’t cross your arms or hide your hands, it makes you appear passive and nervous. Gestures can be a good way to convey your enthusiasm for the job, but don’t overdo it. Practice makes perfect, so run through the interview process with someone in advance and have him or her critique your nonverbal cues. You might have a nervous tic or other bad habit of which you’re not even aware.
