In any interview, you will always get some kind of answer if you ask a question. But that answer will often be numb, automatic, instant, rote, unexamined, even dismissive — and, in the end, useless. It will basically be an answer that subliminally asks, "Can I leave now?"
You cannot settle for that answer. Ask why. In fact, make that the most common question in your arsenal: "Why do you say that?" Accept nothing you hear at face value. Learn to probe. It's fun (trust me; it's one of the great adventures in fundraising, to dig beneath the surface). Most important, it's where you will discover what really matters to your donors.
