Trending @Capgemini; Currently working as B2 CTC 13LPA,yoe 4.4 and working as guidewire developer? Anyone can tell me how to increase my package or get promotion

Even grade C gets lesser than what you are getting. Hikes are very less, can expect 12% if you get a promotion. Else no hikes.

13LPA how much in-hand salary?

What is the inhand salary for you?

I got 5% of the hike after getting promoted to C1, so don't expect much
