When I did interviews, I used to always like to ask, "Why, specifically, did you choice our company?" (Let's you evaluate whether they were just looking for a job, or, whether they had seen something speical about your company that they wanted to be a part of), and, since I was in Information Technology usually interviewing College Graduates ... "What aspects of data processing most interest you?" (Suprising to me were the number that didn't realize the range of applications that were open (from accounting to inventory management to engineering to benefit applications to robotics) or the different skills those might benefit from.)
