Dear aspirant,
As per tentative dates the cap rounds were supposed to start from 9th June or 2nd week and last upto August. This is the pattern each year. Generally rounds start a few days after cet result are announced anyways I've linked out site that contains all the rounds with what you are suppose to do at each round with their tentative dates hope it helps.
