Aurigo Software Technologies Test Engineer interview questions

I went for selenium automation test engineer position's interview they are very punctual ,process started on time. I attended only first round as i didnt clear that round itself. Interviewer asked only programs, java questions. Didnt ask any selenium or testing questions. they are very nice good people,though i wasnt able to reply to his question, i behaved like dumb but still he didnt loose his patience ..in entire interview time he was trying to make me feel comfortable so that i can give reply. he decreased his level of questions what he asked but at the last bcz of my stupidity i got rejected.
