Yeah I bet they send out a hit squad after you each time you put that.
I can see the person looking at the paper work saying "what do I do?"
I have actually seen online applications where the page that asks those questions and claims that it is of no importance it is listed as a "step" meaning if you do not fill it in you app will not go through.
I think they should do interviews over a phone system that also alters the persons voice so you can not tell sex or race by the voice and you also cant see each other that would be interesting.
