Should I leave my oil PSU job to prepare for UPSC CSE?

Hello everyone, I am currently facing a career dilemma and would greatly appreciate your advice and insights. I'm not able to reach any conclusion even after giving it a lot of thought. For context, I've done my Btech in Mech from one of the top NITs and I'm currently working in an Oil PSU (2 years work experience as of June 2024). While the job has been stable and rewarding, I really want to prepare for UPSC CSE as it has been a dream since school days. (Ik many people dream of it) Financially my family is in a comfortable position, which can give me the flexibility to pursue this. However, thinking practically it feels a little risky and scary considering my current job. My current job role requires me to travel frequently and no chance of wfh as well. I'm 24 years old right now, let's say if I give two attempts for this exam that process will take time till 2026. And in case I'm not able to clear prelims of even 2026 attempt, I'll prepare for CAT. In this case: 1. By the time I complete my MBA I'll be 28. Is this too late to enter again in the corporate world? (Might be okay if I get IIMs) 2. If I'm not able to clear CAT, then what would I do? What are my options? (Pardon me if I'm not clear) Has anyone here made a similar switch or knows someone who has? I would love to hear your experiences, advice, and any guidance you can provide. Ps: I've already started my prep with job as I cannot afford to waste time till I make any decision. Thank you for your time and help!
