There were 3 rounds of interview,
General HR, ops, Managerial.
Very easy
Just be confident and answer
It's was phone interview
In HR round they will just check you speaking skills by asking your career background and will ask what do you know about the company.
In ops round they will check your chatting skills.
In Managerial round, will check whether you are really interested and are right candidate or not.
If everything goes will you will definitely get an offer, because they are always in need of candidates as everybody leaves.
Hope this will be helpful
