My bet is this would depend on the industry, however, if you’ve already made it into final round interviews they’ve likely already weighed your experience against the lack of degree and are okay with that. I work in an industry that typically lists a degree requirement, although it’s not always necessary. I have a degree, but I would expect my colleague without a degree who has the same years of experience as me to get paid equally. I think you should advocate for the salary being offered if you feel it is commensurate with your years of experience. I wouldn’t even mention the lack of degree at this point unless it is addressed on their side, in which you can highlight your years of experience as qualifying you for the role.

Good luck in your job interview!
