> Applicants are using AI too. I've heard from people who hire/post jobs that they gets hundreds to low thousands of applications, and maybe 5% of them have any relevant experience.

This happened before "AI" too. When all it takes is clicking an "apply now" button on LinkedIn some desperate people will spam any job they see.

And in some places they are incentivised to do so, as they may need to prove a certain number of applications per-week, or they'll lose unemployment benefits, so they end up applying to all sorts of unsuitable stuff.
