Dear Jeevan,
If you do pursue a Masters in Physics, you could apply for a lot of well paying data science jobs in the finance and banking sector. The average starting salary for freshers is usually more than 10 lacs per annum. A one year Mtech or diploma course in financial mathematics can surely help.
Further if you acquire good software and coding skills you can attend the campus placement as any of your other B.Tech batch mates.
Hope this helps you to take a decision. All the best.
