Tcs system engineer C1 for 2.11 yoe

Hi any folks from tcs , I've just received an offer in hand from TCS giving the above role at 7LPA in Bengaluru. I badly wanted to switch as I'm now having a helpdesk role in my current project and they are not giving project release too but actually I'm a java backend developer.

Please share your thoughts on whether do we get domain specific role like Java and if I'm crossing 3 yoe will I get higher bands than C1 for better advantage.
