From 4.75 LPA to 12 LPA - Is It a Good Growth?

Hi,

I started my career with a package of 4.75 LPA, and after consistent learning and growth, I recently received an offer from Barclays as a Data Engineer with a salary of 12 LPA. I have already accepted the offer, but I am wondering... is this a good package for the role and my 3 Years of experience level? And is there any way I can still negotiate or request a salary revision after accepting the offer?

Would love to hear your thoughts or suggestions from those who have been through similar situations.
