I want to do job in bank but a good post like bank manager so i am confuse to do mba or do bank exams directly after my BE

Hi,
For government jobs you should prepare for Banking exams. For banking jobs in private sector you should do MBA first. That will help you in long term.
Please remember that you will never get your truly managerial role in your first job. You can become manager only after few years of experience whether you join them after MBA or after qualifying an exam.
A cautious note: Anyone, who have sound understanding of banking (specially private banking), or even slightest of knowledge of banking jobs will never like to join a Bank. It is one of the worst jobs available in the market. Today 99% of private bankers have only one job – To sell Insurance. They are unofficial insurance agents of their channel partners.
I am not discouraging you from joining banks, however you must do your research and home work and never get influenced by perception.
Please get back to us if you have any query.
