On Arrival
Always make sure that you are polite to everyone you come into contact with; whilst you may not be remembered for politeness, you will be for rudeness.
When sitting in the waiting room, sit comfortably and fully in a chair. Perching on the edge of a chair or wringing your hands show signs of anxiety and stress. Try to relax. If you are kept waiting, once again, relax - do not show your annoyance.
Make sure that you turn off your mobile phone when you are waiting to go into your interview; avoid making any calls unless absolutely necessary. Instead, use the time to mentally prepare your responses.
