I never did that because I figured that it might be a bit dishonest an I don't want a job offer to be rescinded because of it. I never thought about trying to hack the ChatGPT calls.
None of them ever once actually attempted to ruin the resume again.
Google Docs also allows you to download the document in that format. So, you can even do the resume job from your mobile.
Pandoc + LaTeX has been generally "good enough" for everything I've needed so I don't have much of an incentive to learn.
I'd say go for it! I mean, it's asymmetric warfare, right?
This went around on HN a few years ago and if coffee stains are a plugin, your pixel-keyword-proxy sounds legit.

Or do you just mean, it will silently pass the white text test?
I don't think "humans" look at raw text dumps of PDFs do they? I mean, I don't know, when I've interviewed people I only looked at the rendered output. The goal would be to full the robots; for the visible text I would be complete honest.
Again, I never actually did it.
As to the text dumping -I have no idea. I could believe some of the HR screening tools select all text and dump into some structured fields for review. Probably not, and the trick will go completely undetected.
And I wonder if this argument would fly, e.g. in a court of law: "the information I would like to convey to HR is the one that is readable by human eyes when my CV is rendered by a normal PDF reader (e.g. insert known PDF readers here), anything that is not readable by the human eyes should not be considered part of my CV.".
