Cognizant Technology Solutions — job

Address:

12A, mind Raheja building, Cognizant technology solutions, Hyderabad, Hyderabad, Andhra Pradesh

I got selected in cognizant technology solutions, hyderabad in the month of november, but they didn't released offer letter till now. Even they took certificates xerox twice. Recently i got to know that the facebook process was shifted to wipro. As a result they said that they can't hire me. Now the hr who recruited me even not considering me for interview as i got selected in facebook process so i have to wait for 6 months. But the sad part is the same hr told me that you can attend interview, when i attended the interview the next week he changed his words that i am not eligible for the interview. Although i didn't received any offer letter, he said that i received an offer letter so i not eligible for the interview. Even he didn't checked in his database regarding the offer letter whether i received offer letter or not. Such a irresponsible from that hr asking me to wait for 3 months with no offer letter. It is really pure negligence from the company.
Hope you will resolve this issue.
Thank you.
