I work at Google (the only FAANG company in your list). We would ask about it, but it's not a significant deciding factor.

It might be a deciding factor if you get an interview at all, which team you are interviewing with and for which level. Those decisions are made by recruiters, not interviewers or hiring committees.

And a recruiter is not really looking at your resume as anything other than a wordlist with which to shotgun applicants that might earn him/her commission into the process. And then the engineering team just jumps to leetcode. What's so easy to go missing here is the step where the person is interviewed, as a person, by someone who is not a recruiter or equivalent HR screener, and is technically skilled enough to understand the resume. Ya know, in a word, a good manager.

I don't think internal recruiters (what I believe the GP was referring to) get paid a commission.

depends on firms and their work contracts and definition of "internal recruiters"
