Cognizant Technology Solutions — Offer letter issue

Address:

Mumbai Office Kensington A wing, Hiranandani Business Park, Powai Mumbai 400076 Maharashtra

I got placed in Cognizant technology solutions Genc test in my campus placements. I'm from Ramrao Adik Institute Of Technology, Navi Mumbai. I had received selection list on 20 December and their after in got CDS or Internship choosing options from my Placement cell. As my college didn't allow internship due to regular academic lectures we opted CDS, but their after NO one from our college received OFFER LETTER or any confirmation mail from cognizant. We are now thinking wheather we are going to receive offer letter or not.
Please atleast send us official mail that you got selected. Or give use date, when we will expect offer letter.
Please have a look because almost 70-80 students are in hope?
