I have no idea, but yes, I suspect remote positions are heavily targeted and folks are looking for lazy hiring processes.

But when the job description contains a lot of very general terms (e.g. "scientific computing") and every part of your job history is just parroting a specific term used in the job description with no details it doesn't pass the smell test.

I absolutely respect keyword-heavy job/project descriptions. You kind of have to do it to make it through filtering by most recruiters. But real descriptions are coherent and don't just parrot back terms in ways that makes it clear you don't understand what the are. You find a way to make a coherent keyword soup that still actually describes what you did. That's great! But it's really obvious folks are misrepresenting things when a resume uses all the terms in the job description in ways that don't make sense.

I kinda think we've reach this weird warfare stage of folks submitting uniquely LLM-generated resumes for each position to combat the aggressive LLM-based filtering that recruiting is starting to use. I assume people think they can do well in an interview if they can just get past the automated filtering. I'm sure some are trying to do 3 and 4 remote jobs at once with little real responsibilities, too, but I find it hard to believe that's the majority. I may be very wrong there, though...
