Also 8 vs 10 years of experience is not a significant difference so that HR can BS you.
They are moving quick on you because you're a solid candidate, and they are trying to close quick.
Don't let HR BS you, once you get an offer, counter them at 10-20% of where you want to be, or simply give them a range that you feel comfortable with.
You are the scarce resource, and at an advantage. They've already budgeted for the position at 2 levels above yours, so they have the money. No reason you shouldn't be able to get it.
Be firm, don't accept their lowball.
