Parents pressurising for Govt exams

I graduated in 2022 from an IIT (General Engineer Male) and am working as an SDE in a startup (wfh). The pay, work culture, learning, team etc is good. No complaints. I like my job and am optimistic about my growth and career progression in this field.

But my parents have been pressurizing me to give Govt job exams like UPSC, state services, Assistant Engineer etc. I understand where this is coming from. My parents grew up in a middle class family in the Hindi Heartland (MP, UP etc) and all they have seen are Govt babus who are corrupt, wield influence and respect (Isn't it ironic how our society tends to "respect" those who are the most corrupt). I have repeatedly told them that I don't want to work in the Govt because of it's corrupt system, political interference, poor work life balance, limited freedom to work, strict hierarchies and of course limited pay (also reservation in promotions). Also UPSC is such an uncertain, poorly structured exam ki kab jawani ke 5 saal barbaad ho jaenge pata bhi nahi chalega. Why to waste your most productive youth years preparing for a Govt exam? It might be the case in pre 1991 era (limited provate sector opportunities) but now the opportunity cost is just too high to ignore for a GEM IITian.

But somehow, these reasons are not enough to convince them. I know most of you must have been in this exact same situation. How did you go about bringing this mindset shift in your parents?

Edit_1: Ok, since some people are suggesting me to prepare for UPSC alongside my job, I think some context is necessary. I did not sit for placements in my 4th year as I was preparing for UPSC (I was naive that time, probably was in a bubble and got too influenced by society and parents). Gave an attempt, it did not work out. Decided that I cannot do this to myself and let my prime years go to waste (parents were super supportive here). Then I switched to tech industry and got a full time SDE role via LinkedIn. So, UPSC was my past which I am never revisiting again. But cannot say the same for my parents.
