The choice is yours. I will state the info for both.
BOB: Bank Type: More Retail - More personal/lone customers than business type
Salary: Will depend on posting ( which will be rural in most case) hence salary will come in less in gross figures>
Work: As any other Bank
Growth: Banks will more or less will have same growth pattern and will not differ so as the select one
IDBI: Bank Type: More Business/Corporate
Posting Urban can be rural
Salary: Depends on posting
Work: SInce urban more work but better facilities and liffestyle.
Firstly Ask employees of both the bank and then Make a decision.
My advice ; IDBI
