Thanks for approaching us at [CareerGuide.com!]
Just on the basis of [BCom] I don't think you will get a job in a bank. you may get clerical jobs by appearing for IBPS exam.
I think you should not waste [your MCA qualification]. MCA is required in corporate rather than banks. Banks outsource the IT work to IT companies.
To be best sure of what suits you for your career, I would suggest you to undergo an [online psychometric test] from [CareerGuide.com] which will help you understand yourself in respect of your strengths, weaknesses, emotional quotient, etc.
