Wipro Dot NET Developer interview questions

It was a walk-in interview. Timing was mentioned as 11 AM to 4 PM. I reached at 12 PM. Had to wait half an hour at reception. Then they made us sit in a hall. After 1.5 hour, a person came and accusingly told us that they were calling the names of candidates outside, while our batch of around 40 students was sitting inside. He escorted us out. There was no place to sit for people from our batch, so we stood, waiting. After some time, the interviewer took 6 of us in the same hall. Then this happened for almost everybody of those six: Interviewer asked if we were ready to switch from .net to RPA (Don't know what that is). We declined. He escorted us out.
