When another person arrives after your interview has begun, it's proper to stand and greet the second interviewer with a smile and firm handshake as you're introduced to each other. The only exception to this is when the second interviewer says, "Please, don't get up." This goes for men and women. Men typically were the only ones expected to stand when greeting a man or a woman; however, in a business setting, standing to greet another person is a sign of respect that transcends gender rules.
