A public speaking coach says the best thing about this open-ended question is the opportunity it offers.
Rather than dread the question, think of it as a self-promotional invitation you mustn’t let pass you by. People are not asking for your chronological history, but they do want more than your name, rank, and serial number. Whether you are in a job interview, meeting a new contact while you build your network, or talking with your big boss on a video conference for the first time, this is your moment to shine. It is an opportunity to give your two-minute advertisement about your background, your accomplishments, and the importance of what you do.
