Probably, but to be fair, when a client asks "can you put a button here that sends an alert email when it's clicked?"... a reasonable first question may very well be "what is it you're hoping to accomplish here... so we can tell if such a button is really the right answer". In many cases, the button isn't the right answer. And being the kind of person that digs to find out what the problem trying to be solved actually is... can be very important.

Oh, yes. It's about having a shared culture more than intelligence or knowledge. I know what I will answer if I wanted the job, that does not mean that it's a good answer, it just means that I have the background to know what are they looking for.
