I had prepared for SSC CGL in my early job years, worked really hard, scored a decent 146 in tier1(2017 I think), tier2 was apparently easier for me because of Maths and English. But thankfully I realised it is not worth it and I come from a poor family. I did not prepare/give the tier2 exam.
I started looking for a job switch, switched with good hikes, again changed jobs several times in my 9 years of career till now, built home at my hometown, making decent money in my job now.
If I had joined SSC that time, I wouldn't be able to build home for sure, the salary is too low compared to IT.
Analyse your career options, if you are good and can work well in future then stick to private sector.
If you want secure life then go with govt sector.
And if you want to go in govt sector then why not upsc? SSC post are not that top level, you will be reporting to upsc guys..
Also, i hate reservations, can't imagine reporting to someone who is less deserving and has a low IQ/intelligence than me.
