The truly diabolical way is to add an image to your resume somewhere. Something discrete that fits the theme, like your signature or a QR code to your website. Then hide the white text behind that. A bot will still scan the text just fine… But a human reader won’t even see it when they highlight the document, because the highlighted text will be behind the image.
I wouldn’t do that on your resume. Lots of these systems detect hidden text and highlight it for reviewers. I probably would see that as a negative when reviewing them.
others have given pretty good picture of what you have to do, but you can also do this in some other language, for example in binary, or ascii, and then reduce the font size to something close to 1 pixel. the actual text of pdf is stored in seperate xml tags. Plus you can also write it simply in plain text anywhere near margin of page (no need to do color or size shenanigans) and simply crop pdf out. Cropping of pdf does not remove the stuff, just hides it. Unless you rasterise pdf afterwards and then submit, the stuff is simply there with no special amount of work required.
hypothetically, how would one accomplish this for testing purposes.
Put the LLM instructions in the header or footer section, and set the text color to match the background. Try it on your résumé.
