Infosys interview questions in Basking Ridge

It was a drive at Basking Ridge, NJ and many students came there for different positions. It was a waste of time. There was no proper interview process. There were not enough people to take the interview. They didn't know what they were hiring for and what they required. There was one random lady who interviewed me and I gave all the answers and she was impressed. She went outside for 15 minutes and I could hear her talking to someone on the phone. I don't know what that person told her. She told me to leave and said you will receive an E-mail. I got a reject after 2 days. I really didn't understand what happened. It was a complete waste of time and money. Also, maximum people they were hiring were south Indians.
