Instead of answering this, I will say one thing that would be definitely helpful for a person to decide to go for an interview. People are unprofessional. I feel the interviewer doesn't have minimum culture and common sense and behaved in the most unprofessional way a normal techie can never think. I think it would be definitely waste of your time and I feel with that time saved you can crack a better organization's interview. I did not wait for the result and came back after interview after talking with such a disgusting personality.
