Trending @Cognizant; I resigned this week, but haven't received any communication from the HR team. Also I haven't got the mail with LWD. What will be the LWD ?

exactly 90 days from your resignation submission date

I haven't applied for resignation but I informed my manager regarding my resignation and in order to reduce the notice period I requested them to release from the project and assign in pdp. May I know the notice period in pdp?
