During the interview watch your body language - shake hands firmly and make eye contact as you articulate your points.
Relax and lean forward a little towards the interviewer so you appear interested and engaged. Don't lean back or slump in your chair. You will look too casual and relaxed. Keep your feet on the floor and your back against the lower back of the chair. Pay attention, be attentive, and look interested.
