I have to answer this for a job application form.
While it's a very interesting question, it's pretty tricky to fill in on an anonymous form without mentioning anything that might be controversial/sensitive/personal or prejudice them against you...
So probably no religion/politics/declaring you have 5 small children.... (I don't btw ?)
So:
What is your honest answer to the question?
and
What would you write on a job application form (if it's not the same)?
