Cognizant — didn't get the offer letter even after 4 months since getting selected

I attended the interview for a position in the Java profile in Cognizant on 21st April 2018. I cleared 2 rounds of technical interview and a round of HR interview. In the final HR round even the annual compensation was decided and I readily agreed for the offer. I was told that I have been selected and the recruitment team will get back to me for documentation purpose but since then I haven't received any mail or call for any further proceeding.

One of the leading members from the recruitment team was Farhat Shamim (Farhat.[protected]@cognizant.com) . I mailed my query to Farhat, but I didn't get any response.

Needless to say, this is a clear case of harassment and should be strictly dealt with so as to curb this menace.

Please take necessary actions so that I can get my offer for the position in Cognizant.
