@ST Re: Won't past muster.
That's the problem.
There are so many reasons why and how this data can be abused.
And yes, its so easy to say that you chose another candidate for over half a dozen reasons and there's no way to prove any sort of trend in terms of hiring without exposing a privacy issue of all applicants.
This goes back to the late 80's and aids scare and why there needs to be medical records privacy.
