I've also heard working at such firms has crazy finance hours too, which dissuades me from working there.

Are you an MIT graduate? I am told the recruiters don't accept job applications, they only reach out to people directly to invite them to apply.

I'm a mid career staff engineer & manager, and like many I filter out recruiter cold emails.

Plus I wouldn't let that dissuade me from attempting to figure out how to break in if it lead to x2 FANG compensation rates consistently at the same work load.
