Salary negotiations at Goldman Sachs

Hi all

I currently work at AMEX as a Data Scientist and have around 1.5 YOE. I joined AMEX as my first job from a tier 1 college.

I cleared the interviews for a Quant position at GS and they have asked for my expected compensation.

My current comp is: 17LPA Fixed, 3LPA Bonus

Fresh hires from Tier 1 colleges usually get around 32LPA as base pay at GS.

Should I ask for the same base pay? Maybe a little extra for my 1.5 YOE? Or should my demands be based on my current comp?

This is totally new to me, so any help would be appreciated.
