I might get a new job offer from another department within same company. It's a Fortune 500 company that i'm currently working at. I have worked there for 3.5 years and I did apply to a new position and different role which better matched to my current skillsets and past experience, it's higher job grade - a level higher than my current, I get shortlisted for interview and get through it.

Now waiting for things to be finalised, and I expect HR to offer me with a compensation package in the next few days. For cases like this, how much % increase in salary would make sense for you to jump normally? If i request for 30-40% more than current salary, would it be too much?

FYI, i have a total of 19 years working experience. Out of the total, I have 8 years working in Fortune 500 companies which are into similar role.
