“I check and see if people are registered democrats”
My business partner and I, including management have a couple of “subtle” questions which picks out the liberals in the group during interviews.
I wished I worked for a sensibly ran production company when I was in TV. The overwhelming number of biased liberal managers made me change careers a few years back. However I have found that one of the overpaid and protected was fired and the bonus - bigtime lib female.
