I think I know where you're going, but the point of this question is that it is unexpected, which demands honesty from people in most cases. You can't trust a recruiter's answer, but if you're a programmer being interviewed by programmers, you can usually trust the answers.

I'd also be interested in the answer to that question from a first-line or second-line manager. Whether they answered it honestly or not, the answer would likely be helpful as part of the interview.
Oh! If someone asked me that question, I would describe the one change I would like to implement the most! You're exactly right, there are a few things you can measure with this question.
