Its a one day process. You'll get an invitation for an exam. I took the exam for 2 to 3 hours. Once you passed the exam, there will be an initial interview; mostly basic interview questions and finance and accounting terminologies. Once you passed, there will be a panel interview, composed of team managers. They will ask questions about your resume, finance and accounting terminologies, some situational and behavioral questions.

The interview had 4 stages. Technical exam, HR interview, Technical Interview, Final Interview. Everything is manageable just listen to what your HR says. Review basic finance question and terminologies. For the final interview, it's most likely aptitude and how do you react on a situation.
