To be fair, in an in-person interview talking about something like this can be a nice way to settle into the interview and steady any nerves they might have - it's a question that doesn't have a wrong answer and doesn't (or shouldn't) have a "gotcha" attached that the candidate can be afraid of. It can spark a little conversation that could lead to other, more specific topics - but if it doesn't then no worries, it's served its purpose.

It's a bit odd to be asked to write this out ahead of time though, because if when it comes up in the interview it's like you're being questioned by the police on a statement you had previously given them and being tested what you said. Weird.
