Deftsoft Informatics Business Analyst interview questions

I have given a interview here. And the the person who was taken an interview has no manner at all. He was just wasting my time and asking me a question which was totally base less. And asking me a question which is not from my field. I've given alots of interviews but no one behave like this. I was so pissed of by their behavior that after some time I have another interview which was get ruined. Just waste of my time.
