Dimesnion India interview questions

After waiting for more than 1 hour, a written question paper was given with multiple choices. Questions were basic fresher level PHP questions. Once again waited for another 30 minutes. which was very very bad, because it should take max 10 minutes to evaluate a multiple choice question answers. Then was called for face to face tech interview. it was for approx 30 minutes and again waited for 1.30hrs, I asked 2-3 times if i should wait or leave, they didnt respond. after waiting 2 hours the HR Priyanka was seen there and I asked repeatedly about my status. Then she told me that - oh i am sorry. you leave for the day, we will get back. really the interview process was very very worst it's more waiting than interview. nobody is responsible there.
