Hello Akash!

Yes! you can absolutely get a bank job after engineering because as far as I know, bank jobs have their own exams. They don't care whether you are an engineer or doctor. So, yes you can. People feel like they are wasting their degree but my personal opinion is, you can do anything that makes you feel good.

All the best!

Hello

while ding engineering give bank  Clerk exams every year along with other govt exams this would increase your aptitude and reasoning along with your engineering knowledge. Your might also get selected in one.

After your engineering just go for PO exams which require graduation and your can get selceted in a few tries.
