Salary Advice Needed for Senior Data Scientist Role at Fractal Analytics (Grade 6 vs Grade 7)

Hi everyone, I’m currently in the interview process for a 'Senior Data Scientist" role at Fractal Analytics. I’ve cleared all the technical rounds and have my HR round coming up in a few days. The HR who initiated the process mentioned that I might be placed in either Grade 6 or Grade 7, depending on the panel’s decision in the HR interview.

Could anyone help me understand what salary range I should ideally ask for in each of these grades?
