Cognizant Technology Solutions — Offer Letter not released for almost 3 months

Address: Bangalore

Hi Team

Hope you are doing good.
I am Avinash.
I have attended two rounds of technical and manager interviews on 1st September and then they delayed the process till next month from 1st notification of 2nd round on 9th september, finally giving the confirmation of 2nd round on 8th october 2021 and got confirmation saying to submit the CIS form to proceed further, then I have submitted the CIS form with required details and replied back.

Later after around 13 days on 25th oct 2021, I got HR call and discussed about my package and designation, after that HR confirmed that they will release my offer letter after confirmation and approval. One point to note here is that initially when i was contacted by their third party HR, i was told that there is no salary constraint and now after all the interview rounds are done, they are waiting for confirmation, It has been almost a month, not sure how much time would a confirmation would take but process is delayed very long.
It has been almost 3 months now that the interview process had started off and still I haven't got my offer letter and also they are not giving any timelines.

Please help me in getting the offer letter.

Thanks in advance.
