To become a Bank Manager which course i should be taken.
BS Management or Finance can help you in this field. If you are a newly grad, it's not given that you'll land a manager job right away. Most of the time, the hiring manager looks at the experience and qualifications. Be prepared to come in as a non Manager and through hard work and dedication, opportunity will come -- either promotion or applying for that position once you have enough experience in the field of banking.
Best of luck to you!
In general, for front line staff, they may look for talents who have business related background, e.g. Business, Economics, Finance, Accounting, etc. For the aforementioned support functions, they may look for the subject matter experts of that particular function.
First of all, I would suggest you can do more research on the business or function you are interested and speak to someone who are really working in that area to acquire more understanding. You can then start from choosing the subject as your major in the college. You also search for working opportunities to work as an intern. This could really help you to determine whether it suits you or you are really interested on.
Hope this help!
Going directly into management is rare, but starting at a bank obtaining experience will lead you to a bank manager role.
