Cognizant Sr. Associate interview questions

I have received a call from a recruiting agency to attend an interview in CTS for UNIX and SQL. I have been asked to report before 10 AM in CTS Office in Kolkata. On the day, it was like a walk-in on various technologies and 2-3 people from recruiting agencies were sitting in a desk for different technology openings. Unfortunately the UNIX recruitment agency team arrived at 11 o'clock and then we need to fill up a form. I was probably the second person for UNIX interview and I have been called for the interview at 2:30 PM. The interview room was one of the cafeteria, where interviewers were sitting on different tables and one by one was asked to enter the room as the names were called. When my turn came, I have been indicated to the table and person who will be taking the interview. By the facial expression it seemed that he was not satisfied to take the interview since he was about to go for lunch. Even he was not proficient in UNIX and started asking on PL SQL on his own technology. I have given the answers as per knowledge without trying to explain him that he is supposed to take the interview on UNIX as written on my CV in bold letters by the recruitment agency. The interview was hardly of 5 mins which was not a surprise for me and I have been asked to stand outside. After 2-3 mins one person who was calling out the names for interview was consulting with the interviewer and giving the status to every candidate. I have been informed that I have selected in the round and for next round they will arrange interview over call which will happen in next 15 days. After several chase ups from January last, I have never been called further after repeated chaseups. It was really a pathetic situation when such companies arrange for walk-in with lack of planning. Hats-off

2 Technical rounds happened on Starting of February, no calls still, Technical Panel said 2 technical rounds got cleared, but HR was saying waiting for Client update, 2 days before received an email saying your resume do not match us...such a cheat,..without Resume match how can they have 2 technical rounds
