While waiting to be interviewed, sit properly and behave as if everyone passing you by is your potential interviewer. They just might be! Smile at people as much as possible. Do not act impatient or bored, it sends the wrong message. Some interviewers will keep you waiting just to see how you handle yourself.
Greet you interviewer with a firm handshake and a smile.
