As an employer I would want to block this in an instant. It's the perfect addition to any social engineering arsenal. If it works, great for finding out little details about a company that only an insider would know, to support a more thorough corporate espionage or hacking attempt.

Also, given that out of the volume of incoming queries that companies get only a tiny fraction is related to potential employment there, you'd have to figure out how to filter out people looking for 1) sales leads, 2) customer support, 3) freebies, 4) a direct line to the CEO for their complaints, 5) a direct line to the CEO for their charity sponsorship, etc.

Sorry about being harsh. I just think it could be a bit of a Pandora's Box.
