I interviewed with the CEO as part of my final round. He was obnoxious, rude, arrogant, full of himself and even insulting. He asked a bunch of questions that were illegal too. He had his feet up on his desk the entire time he spoke with me. I have never felt so humiliated before.
It's disappointing to see such a great organization being headed by someone who behaves like him. I'm surprised anyone accepts an offer after going through an interview with him.
