Not asking if they're happy with their life/job/etc, but whether or not they find value in the work they do. What the nature of that value is should be in the answer. And the answer will invariably touch upon a lot more than job satisfaction, so you don't have to ask so many questions if your time is limited. Doesn't always work on the phone (I find people are often guarded and overcompensating), but in person this question can be disarming and quite revelatory.
