> They specifically asked personal questions - parents stuff, relationship, etc.
In the US any employer who asks you about personal relationships during an interview is opening themselves up to an illegal discrimination lawsuit.
Even just an IQ test [1] or teacher licensing test [2,3] opens them to illegal discrimination, so that's not saying much.

Which protected characteristic does "personal relationships" fall under? It's vague enough to mean almost anything you want it to be, and I struggle to imagine any sort of successful prosecution.
