Apple levels and compensation

I am currently interviewing SWE role (title: Senior applications developer) at Apple. The roles does not indicate weather it is at ICT5/6 etc.. I am also interviewing for staff software engineer at Google (recruiter told me this will be at L6) Levels.fyi says ICT4 is senior roles for ICT5 etc.. there are no titles. How does Apple decide on levels? I have over 15+ years experience predominantly in financial services within front office roles. My previous job title is Principal SWE. #apple #google
