Yes, I understand this to be your argument, but I simply do not believe most hiring managers (really: any hiring managers) seriously gauge "depth" and "personality" from the answer to this one question. That's what makes the question such a trap for candidates: it's intrinsically unimportant (the data you pretend it collects simply isn't present for most candidates), but the "wrong" answer can be very harmful.
Candidates should simply dodge this question. The more I've thought about this thread, the more cut-and-dried my judgement on this is.
