Cognizant Software Developer interview questions

Bad experience. I got a mail from the company saying it is a scheduled interview ( Oct 1st 2016) for .net developer but once I reached I saw like 500 - 1000 candidates waiting in the queue just to submit their resume. Two rounds I had 1 technical and 1 managerial. I cleared both the rounds and was asked to fill the employment details form. Later I was told that I will be receiving a call from HR within a week. It's been 3 weeks now and I still dint hear from them even after lot of follow ups. No response for mails and calls as well. Many people say CTS does this for lot candidates. They will misplace your resume or they will forget it.
