Deloitte Audit Assistant interview questions

I received an interview, which I obtained from the process at the university I graduated from. I had a first round and a second round interview, with many happy hours and meetings to get to know the culture of the firm.

First we had Aptitude test, wherein we were tested in Accountancy, Costing and general aptitude. Next was Group discussion. We were just 6 to 7 members in one room out of which 5 of us got selected for next round. Random topics were given to speak. It was not subject specific. .Finally we had HR round.
