As someone for whom the answer is always 'money' I learned very quickly that a certain level of -how should I call it- bullshit is necessary to get the HR person to pass my CV to someone competent. As I am not as skilled in bullshit as I am in coding, it would make sense to outsource that irrelevant part of the selection process, no?

Maybe it makes sense for you, however from their perspective, it's not an "irrelevant" part of the selection process, but the most important part.

You can use an AI assistant to help you fix grammar and come up with creative reasons why you should work there.

This adds another twist, since I'd bet nowadays most CVs are processed (or at least pre-screened) by "AI": we're in a ridiculous situation where applicants feed a few bullet points to AI to generate full-blown polished resumes and motivational letters … and then HR uses different AI to distil all that back to the original bullet points. Interesting times.

This makes me think about adversarial methods of affecting the outcome, where we end up with a "who can hack the metabrain the best" contest. Kind of like the older leet-code system, where obviously software engineering skills were purely secondary to gamesmanship.
