I’ve never been able to understand why these companies hire these kind of people in the first place. I’ve been involved in hiring workers for 35 years at various companies and have always been able to get the person that I wanted. With a bit of due diligence such as background checks, calling references, word of mouth and some intuition you can weed out the undesirables before you get to the interview process. You NEVER want to publically say that you don’t want certain types of folks. Those folks just get a nice letter that says that they didn’t make the cut for an interview and thanks for your interest.
In Texas it is normal to give no reason. It’s better that way really.
