Remember that it’s not only the hiring manager who makes the decision on who to hire. Be polite and gracious to everyone you meet from the time you walk in the door to when you leave. The people you meet could be your future co-workers, so make the best impression on them that you can.
When you arrive, introduce yourself to the receptionist. Make sure you know the interviewer’s name and use it as soon as possible during the interview. If you’re not sure of the name, call and ask prior to the interview.
Turn your phone off and put it away before you walk into the office.
