Before you go to technicals,
Choose whether you want to be in commercial banking or Investment Banking.
You should be able to give a good reason as to why you want to be in that particular field at the same time you should be able to relate the CA subjects with it i.e. you should be able to explain how CA helps you in that field.
If you choosed commercial banking, decide whther you would want to be in risk mamangement, treasury operations, corporate finance, Basel II, structuring and selling financial products etc..??
If you want to be in Investment Banking, decide among Stock/Sector Research, M&As, fund management, front office - trading and sales, fund raising, asset management, or into bonds and derivatives...etc?
After you do the above, let us know your choice out here or on a different topic of CAclub, and I am sure you will get a much better response.
Wishing you good luck for you results.
