As you know that IBPS exam has became common for applying for bank exam as 19 banks comes under IBPS.
Other than that SBI is also recruiting separately for Clerical / Assistant posts.
For getting a Bank job you should be perfect in the following topics:-
Verbal and Non-Verbal Reasoning
Marketing Aptitude / Computer Knowledge
If you are perfect in this above topics then easily you will be get selected.
My advice is you just take admission in best coaching institute and practice atleast four hours a day.
All the best :)
