Hello,


You don't necessarily need to take BBA to become an investment banker.Engineering graduates can also become investment banker.I can help you better you will let me know from which stream you belong to.
As for know i would say its don't necessarily require to be from a specific stream to persue it as a carrier.
A bachelor's degree is the minimum educational qualification required to work as an investment banker. Entry-level analyst positions in the field are typically open to bachelor's degree  graduates, and it is possible to move on to a senior banker role without a master's degree in many investment banks.

I hope this helps.
