Background about myself

• B. Tech from Tier 1 (One of the old IITs)
• Non Circuital Branch
• Secured PPO at Largest German Bank as SDE role.(22 CTC 15 Base)

Now I am quite confused about my career, like I tried SDE and secured a job in it but i am not quite interested in SDE rather than I find finance roles more interesting where i need to deal with Statistics. Now I have accepted the PPO and want to make max out of my college life remaining. Also I will be joining a Bank and want to move in finance world, can you please guide me how to use my remaining time to fully prepare for finance roles? Also is there any pathway should that i need to follow, any degree i need to pursue or exams like CFA,FRM to crack roles in Front office ( Front office roles).

Please guide...
