Cognizant — I didn't receive my offer letter after given my hr interview

Hi Team,

I am waiting from 11th December for my offer letter after HR has confirmed that they will release the offer letter in fourth week of December, but now it's been almost a month but still didn't get the offer letter. Atleast please confirm status of the letter whether it will take time or it is in hold or if rejected. It is very unfair to keep already selected people to keep waiting these many days without any update regarding the status. It would be helpful if you could provide an update at the earliest.

Thanks & Regards,
Manasa Poloju.
