One interviewer, showed up late, then gave me “homework” that done properly would take 40 - 80 hours of work. The only reason I didn’t reject it outright is that a friend who worked there referred me, but later we talked and agreed I wasn’t going to do it.
A friend of mine once went for a CPA interview where the HR person’s first question was, “If you were animal in the forest, which one would you be?”
He looked at her for a moment, and replied, “I can’t work in a company that thinks this type of question is a job qualifier.”
He got up and walked out.
