I'd have thought that was SOP just to try to ensure the application was genuine and that her answers tie in with those put on the application a bit like how they now quiz all applicants applying for their first passport.
My friend always used to make Indians/Pakistanis applying for operative jobs at his firm fill out the application form in front of him just to ensure that the one they brought with them hadn't been filled in by their mates. I guess nowadays there are laws to prevent a diligent employer doing this - he's not bothered he's got plants in Brazil, Czech & China now where political correctness doesn't apply.
Good luck with the application !
