I would just like to add on to the wonderful advice by @thistooshallpass.
You haven't told us your age but assuming you are somewhere between 21-24. I would advise you to work at Accenture for 1 or 2 years. You might end up liking the job. meanwhile, start saving for UPSC prep as much as you can. if at the end of 1 or 2 years you don't like the job then leave and prepare full time with the savings you have. UPSC exam is highly unpredictable more so because of the preliminary examination. so save enough so that you can prepare in peace.
Dev team welcomes you.
