Hi leena,
Considering the fact that you are a youngster, I would say you go for UPSC, a person who has cleared UPSC examination is seen different in the Indian Society. UPSC provides a lot of job opportunities to serve the people and the amount of satisfaction it will give while doing so will be incomparable to anything.
Although banking jobs are also good and quite reputed and can serve as a decent way of living but none can be compared to the father of all the jobs - UPSC ! Since you are young you should atleast give it a try for as the saying goes 'the preparation alone of this exam makes you a different personal overall'.
But don't just blindly follow this suggestion as for clearing upsc, according to the toppers your 'WHY' should be very strong hence take suggestions from your parents, teachers and finally make up your mind to do something that is best suited for you.
Regards.
