mathematically, your chances can be determined by the number of applications you submitted to the bank establishments over a period of time. Commonly, chances are slim if only few applications are put to forward.

Persistence is the key but is not the only factor considered. You must also have the exact qualifications (to match with what is being searched for the open position) to compete with other aspirants.

It's not going to be easy but you need to keep trying.

GOOD LUCK!
