What kind of package can you get as front end developer at google?

I’ve heard that it is pretty hard to get higher title/TC if your expertise mostly focuses on front end at google. Can anyone confirm? I interviewed with them about 2 years ago and get L4 with about 300k TC…… I have about 8 years of experience although mostly in non-fang company... The level was a bit disappointing so I didn’t end up taking the offer back then. As I am now rethinking about interviewing with them, i want to make sure I have realistic expectations and do everything I can to get higher title/compensation Any benchmarking information or tips will be appreciated!
