This question typically allows you to set the tone and expectations for the rest of the interview. This is your chance to deliver your presentation, or elevator speech, of who you are as a professional, how far you've come in your career, what led you here today, and where you hope this opportunity will take you. Your interviewer has a vested interest in getting to know you as a person and as a professional and getting a sense of your personality. This will help them assess how well you would potentially fit into their culture and collaborate with their teams. So before your interview, prepare a brief bio that covers all these points, relax and be confident in how well you've prepared for your interview, and put your best foot forward.
