The interviewer is asking this open-ended ice-breaker question looking for some introductory information from you. Give a short and engaging response, ending on an interesting note so that the interviewer wants to hear more. At this point, it is more about your personality and ability to give a concise answer than the amount of information you expose. Always tell a story, start by telling them briefly of your past education, and then your past work history, ending with your graduating with your degree and starting your new career. Usually, you would leave out any personal information about yourself, never discuss your age, marital status, children, where you live, hobbies, etc. They are wanting to know about you professionally. Many of those personal questions are illegal to ask in an interview.
