Tata Consultancy Services Dotnet Developer interview questions

Disappointing as the Technical Interviewers were confused between JAVA and .NET Keywords and concepts. They sent mails but the turnover applicants were over 90 and they were not able to handle this volume. We had to wait for over 8 hrs just to have a 5 min interview which was again -disappointing, Extremely shabby and uncultured behaviour of those responsible for this wastage of employed people who took leave to attend the interview. Disappointed with the overall experience with those responsible for conducting this interview and the interviewers. Please learn the difference between walk-ins and interview calls.
