This guy obviously does not understand the distinction between advisor and decision maker. He also missed the class about not embarrassing your boss by under cutting his programs. Lastly he missed the lecture about who was elected verses who is appointed.
I was taught early on to never bad mouth a previous employer during an interview. And really don’t do it if you get hired. How much stronger would the admonish be if they were referring to your current employer?
Only an idiot or mole acts like this
