First I got interviewed by the HR (at morning time). Next would be Panel interview (same day as with the HR interview but was scheduled at night time). And the last Interview is with the Hiring Manager (scheduled the next day after the HR and Panel interview).

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.
