I think this is a good idea but the more popular you get the more filtering you need. If 1000 hire-ees want to meet for coffee how will the hirer filter them?
Well I guess I like the idea from the hire-ee perspective. But isn't it a bad deal for the hirer? How does he know I'm even worth talking to? The most valuable asset we have is time and you are asking people running companies to give a lot of it away.
