I’ve always found this question particularly difficult. It’s so open-ended you could go in a wide variety of directions with your answer.
However, Mark Goulston, M.D., author of “Get Out of Your Own Way at Work...and Help Others Do the Same,” advises, “Your answer should show that you have checked out the position being offered, the company and what it seems to be trying to accomplish now. It should also show a self-awareness of your skills, what you’re great at and what you may need additional training in. Also, people are interested not only in what you know or can do, but also what you have already done that produced a positive, measurable result for someone else. Don't talk about personal stuff unless asked specifically. And if you do, the interviewer wants to get a sense of your values, attitudes and how you spend your time.”
