Probably not entirely fair. e.g. After enough sentences it is trivially easy to identify LLM output. So you repeatedly get the opportunity to test a sentence or two, guess the provenance and then realise it is the first sentence in several paragraphs of generated output.

without external validation, you still just have a gut feeling. it doesn't matter if it's the first or thousandth.

I can tell if somebody ate cornflakes or oatmeal for breakfast just by looking at how they walk. I'm always right. you better believe me. I've seen thousands of people walk.

If the cornflakes had been sitting in old milk for a week, then yes, I would believe you could tell by how they walk, either hunched over with a cramping stomach or with shit pants. LLM text is quite similar.

Yes because it would be completely different if it were oatmeal.

If the oatmeal hadn't sat in old milk for a week, yes, it would not likely cause gi distress

and yet if it had, it would.

Let's make one of your breakfast foods eggs. Sometimes you won't notice from the walk if they just had normal eggs. However, when they are also rotten and were over indulged in, you can tell from the person's walk that they ate them for breakfast and due to the noxious sulfur smell emanating from the diarrhoea in the person's business casual slacks, you can tell with a high degree of confidence it wasn't the rotten milk cornflakes, but one of a very few number of sulfur-rich foods, probably eggs.

Bad human resume text and overuse of unmodified LLM output are both detectable, but they are detectable because they are bad in quite different ways.

Regarding the original resume reader's notion that they can detect LLM text with a high degree of accuracy, it is not their LLM output detection specificity I would take issue with (similarly, despite stating validation is critical, I would bet you, too, are pretty confident when you see an entire page of blogspam or marketih copy that you regard as LLM generated despite it rarely being marked as such). Rather, it is their sensitivity, as I am sure occasional use and especially slightly modified output from LLMs gets by them now and again without them knowing.
