EY Tax Analyst interview questions

I applied through Employee referal and i was interviewed at EY, bangalore. There were 4 rounds; 1st round was GD we had to choose a topic and speak about it for a minute, all general topics were given (smart work vs hard; is IPL a boon to cricket; Love marriage vs arrange marriage; Course or College which is important). 2nd round we had to write an email in 75-100 words and next was Aptitude test for 60 minutes, there was 3 sections(Accounting, Analytical and Numerical, Verbal) each section had 20 questions. 3rd round was HR, it was just a casual talk with the HR and few accounting question. After a week i got a call for the final round. 4th round was managerial round, all basic question about accounts and tax, few analytical questions like 1 kg of gold or 1 kg of cotton which is more. I was also given a case study to solve. Still waiting for call.
