Cognizant — offer letter not released by cognizant 2019

Address: home address, 560019

Hi,

I have attended the interview on feb 9th 2019 for datapower skills in bangalore and have cleared all the rounds including hr discussion. Initially i have got couple of emails where asking me to provide me the details and upload the live picture. Later there is no updates and even the hr is not responding properly.
Contact person will not even pick the call and it is very difficult to follow up with the team

Thanks,
Akhila vinay
