tin my case there were total three rounds technical, manager and HR.basically if you cleared first technical round you will go through. after third and final round they asked me to submit my documents to process the offer letter. once i submitted required documents they released my offer in 1 day.

Simple 3 rounds , 2 days process.. second day interview will be held the whole day without break. HR round was document verification round. Communication round is 1:1 round with questions like tell me about yourself, last movie you saw.
