Telephonic, aptitude test followed by an survey form and then 2 interview back to back if selected in 1 then only you will be able to give 2nd round of interview.

There are 4 rounds which include Profile briefing, written test, manager round, and HR round. where i have cleared all of them and they told to wait for the offer. but they did not release it and there is no response from them when i tried to contact.
