Cognizant — delay in issuing offer letter

Address: banjara hills, Hyderabad, Andhra Pradesh, 500073

Hi,

I attended an interview at cts pune (Icc trade tower) on june 22nd 2019 for sap security & grc and cleared all the rounds. At the end hr informed me that i will receive my offer letter in a week but i haven't received yet. Meanwhile i received an email from cts talent acquisition to upload my photo in one of their portal. After that, i got one confirmation mail, after that no response. I am not sure if normally they would take almost a month to release the offer letter.
