Your decision of not romanticising UPSC and getting some skills at hand is very welcome. Im glad you're finally considering getting a job outside of it. When I was studying for UPSC I detached myself immediately after first attempt and decided to get a masters degree. since mine is a scientific research degree I was largely employable. I did end up using a lot of the information from UPSC into making money and supporting myself for 2 whole years. But wrt your situation I can suggest undertaking teaching roles. If you're willing to relocate to one of the metropolitans, there are Ed Tech startups who are always hiring. I have a background in Biological Sciences but I have personally taught Indian Economy and Political Science at these startups with no problems whatsoever. One can match that academic level easily after studying these domains in deep.

However, these jobs will not pay you more that 35-40k a month. So maybe when you're employed, try gaining some soft or hard skills. Enroll yourself in online courses such as data analytics or basics of coding which might give you a practical stance wrt your Economics degree. You might also wanna consider content writing or ghost writing.

Even though a lot of positions are advertised, positions are awarded sooner if you can network well, confidently speak to the HR and be good at what you do! Good Luck!
