Person A applies for a job at Company, Inc. My wife wonders how Person A heard about the job opening. She Googles Person A and sees a link to a Facebook page. She navigates to that link and sees that one of her ‘friends’ is Person B, who just so happens to work at Company, Inc.
Very little effort on the part of an amateur sleuth, and she was able to ascertain, (or assume) that Person B directed Person A to apply at Company, Inc. What struck me (like a thunderbolt) was that none of this was any of my business! And it’s out there for all the world to see.
