How much is variable bonus at c11 level?
I had an interview with Cognizant and then got an email from HR to fill in CIS form and also along with to send all the documents. After i send all those details i got an email saying the position went on hold and to wait until they revert.
Any idea that how much time it would take for the position to be released? They did not respond when i asked the same question.
