If you're the interviewer, there's a lot you should already know: The candidate's resume and cover letter should tell you plenty, and LinkedIn and Twitter and Facebook and Google can tell you more.

The goal of an interview is to determine whether the candidate will be outstanding in the job, and that means evaluating the skills and attitude required for that job. Does she need to be an empathetic leader? Ask about that. Does she need to take your company public? Ask about that.

If you're the candidate, talk about why you took certain jobs. Explain why you left. Explain why you chose a certain school. Share why you decided to go to grad school. Discuss why you took a year off to backpack through Europe, and what you got out of the experience.

When you answer this question, connect the dots on your resume so the interviewer understands not just what you've done, but also why.   _{Your Comment}
