Cognizant — offer letter not received

Address: Manyata techpark, 5600059

Hi,

I attended an interview at cts @ manyata tech park on march 9th 2019 for automation testing position and cleared all the rounds. And i received an email from cts talent acquisition to upload my photo in one of their portal. After that, i haven't received any updates. After follow up with hr also did not get any mail. I am not sure if normally they would take almost a month to release the offer letter.
