I am writing this with the agenda to seek advice on my initial step that I plan to take.
To give a bit of background; I am currently working as a Software Developer (SDE-1) at A****n for the past (almost) 2 years, where I joined just after my B.Tech. (in Mathematics-and-Computing) from IIT Guwahati (DR-2). I have never liked my job as such, as it involves coding, which though was part of my 4-year curriculum but was the one I enjoyed the least, instead I mainly focused on Mathematics and HSS courses.
Initially, I thought of pursuing masters or PhD (in Computer-Science), following the usual track of the ones with good academic background and 9+ CGPA. However, I kept thinking and the first year of my job got over (with bad performance review, which I was able to fix later). Post this, I started thinking and realized that I would land up in a similar situation if I go for higher studies in CS. So, the better choice was to think of Maths. I looked and discussed with friends, but was never sure of pursuing PhD as I never tried to build a research profile during my under-grad. This made me explore other areas: fellowships (YIF, LAMP), job-switch, MBA, and UPSC.
Job-switch, I felt would be cheating myself as the problem is not with the company, it's with the kind of work (coding) and my acceptance of it. I could introspect that I want a job where I am able to contribute (either impact-wise or through my maths skills) and there's a genuine appreciation/feedback that I am able to see: teaching, civil services, counseling. During this time, I came across a few people (my teammate, my batch-mate, my senior) who were pursuing UPSC. I got reminded of my childhood days when my parents used to tell me to thing about IAS, but dropped later as I didn't follow news and current-affairs. But, this thought got reignited and I started thinking. And my unsatisfactory work-life also kept me thinking more to explore another, more fulfilling, option. I talked to the ones I knew, saw the financial situation, analyzed the current work situation (pressure to perform next level tasks) , and talked to my parents (a few days back): they are surprised, but supportive and are okay with me to give a try, but worried as I am talking about leaving the job and preparing as a total beginner (who never sincerely followed Current affairs), and that this might be the decision taken in haste to try anything apart from the job.
The way I analyze the situation: I will have to work very-very hard, to study the subjects and to build a habit of following current affairs (which I have already been working towards). Given there are only 11 months left, and the job is psychologically tiring for me, preparing along with job would be extremely difficult and I would most probably screw up at both the ends. Even, if I decide to prepare alongside for 2 months, then it would be 3 including 1 month notice. Without job, I get to stay with my family in Delhi (Mukherjee Nagar itself), which would ensure support and emotional balance to put all my focus on the preparation, instead of living 2 false lives). And the worst, if I actually am not able to tackle the preparation pressure, and find that this was a wrong decision, I could still restart and try for a job/higher studies, but would be much relieved to have tried and then realized.
My friend and colleague who quit for UPSC (he had been thinking since school time) understands the practical and psychological situation and suggests to try. However, given how risky the step it might be that I take, I seek for the opinions of the ones here who might have faced a similar situation.
