First stage is interview screening, second is call with recruiter, third is case completion while viewed by manager. I am not aware later on as I have not yet completed the third stage

First off, a standardized computerized aptitude test which can be taken from home should be taken - the link was sent through email. The test takes around 10 to 15 minutes. After that, one round of HR interview with behavioural interview technique was conducted - taking approximately an hour or two. The next round is with a manager / senior manager - who asks questions about auditing techniques, IFRS etc.
