From what I've been told this guy was nothing but rude and abusive, an they way he treated a keen wannabee is disgraceful an the guy should be ashamed!
Maybe this was part of the interview, especially if job involves customer service.
The only illegal questions in the application form was the marital status (you should refuse to answer) and the date of birth (put in only the date, not the year). And the part about smoking and drinking should also not be answered.
