> randomly stating who you are
it's not random at all. that's literally what the resume is supposed to be and what the hiring manager wants to know! This is a real human hiring manager sharing candid feedback on his acceptance criteria. So there's at least one company where this is pretty sound advice.
your point about the dumb filters is plausible but at some point a human is going to read it and try to decide if they want to work with you. If all they have is some AI output, it's going to be an easy no.
>what the hiring manager wants to know
In perfect information theory, yes. In practice we some HN article where on the fifth round some FAANG wants the applicant to juggle dry erase markers while reversing a hash algorithm while standing on their head.
Multitudes of companies use hiring agencies, and at least from what I've seen these agencies are more about numbers than quality. An AI application that overstuffs your abilities is far more likely to be observed than the resume of an earnest person.
Hell, worse than that, there seems to be a growing industry of companies that just put out job listings as a means of collecting information on people and selling it off, rather than providing any kind of job.
