Per level salary bands are easier to figure out for FAANG companies with sites like levels.fyi. You may be able to get an understanding during an interview, probably best to ask a recruiter since they are in the HR department and may have more detailed knowledge. Obviously don't ask "I want the lowest level with the highest salary" but more along the lines of asking how promotions work with titles/levels, annual reviews, etc. because those are relevant things to know and the answers may help decide between one company and another.
All salary bands overlap, a company with a lot more people will have a lot more variation in salary per level/title.
