Two smart questions to ask in a job interview:
1) What was it that prompted you to want to interview me?
2) If you hired me, what would I accomplish so that in a year from now you’d feel that hiring me was a great decision?
Psychologically both questions force the interviewer to visualize you favorably (this is known as pre-suasion). From a functional perspective, the answers to both are useful in determining what’s important to the interviewer, and whether the work itself is compelling.
