Salary Discussion for Boston Scientific

Hello everyone, I'm glad to inform everyone that I'm expecting an offer from Boston Scientific, Pune. My current package is around 22 LPA and until now I was expecting around 35 LPA. I consider I was very underpaid in my current company and was not given any hike last year. I have 11+ years of experience in Mostly Backend+some frontend development and leading a team. I searched over the internet and this company may provide up to 39 for my level of experience.

Please suggest how to approach the higher package.
