I would not bring this up as an interview question.
As you can see from this thread, a large number of clinicians basically equate pimping with asking questions, usually in a clinical setting.
So by asking this question, you're running the risk that an interviewer will perceive it as "I'm afraid of being asked questions or tested on my knowledge base"
Further...it's a useless question. if any interviewer tells you that his/her school does not use pimping, they are lying to you. There is no school that has a categorical ban on pimping, nor would any school have control over the vast number of teaching faculty and residents to be able to enforce such a ban. Every school will have people who pimp.
The fact that it is not referred to as the Socratic method, but rather as "pimping," says a great deal. This suggests to me that the Socratic method is being poorly used by some number of those in a position to lead and teach. . . and this smacks a bit of some of the problem spoken of in the Double Suicide thread.

Just saying and considering. . .
There is often a negative connotation to the term pimping, and as
@LizzyM said above, it is sometimes done (or at least perceived as) in order to belittle/establish the hierarchy.
I don't really like pimping, and have tried to get away from it, because for the most part I think its a lazy teaching method. It can be done well, in a truly Socratic fashion, but that is harder than you think (my department chair is a master of it).
That doesn't mean I won't ask questions of a student by any means, just that I'm trying actively to expand my teaching toolbox so to speak. Pimping as done by residents is often ineffective - they have a limited number of esoteric questions that they ask just about every student because it puts the discussion firmly within "their" knowledge base where they feel comfortable establishing their superiority over the student.
