Mind your body language

1. Do not keep shifting your position.
2. Your posture during the interview adds to or diminishes your personality. Be a little conscious of your posture and gestures. They convey a lot about your personality.
3. Sit straight. Keep your body still. You may, of course, use your hand gestures freely.
4. Avoid these mannerisms at all costs:

 - Playing with your tie
 - Theatrical gestures
 - Shaking legs 
 - Sitting with your arms slung over the back of the adjoining chair.
