Tata Consultancy Services Programmer/Analyst interview questions

First there was an aptitude a email writing round. Post that the interview process started. 10 interview panel at one place, clumsy surroundings when 40 people talking at the same time. Random selection also happened. They just don't care about your C. V. Three person asking different question to same person at the same time, which one should one answer first! Overall it was a waste of day.
