Because your bot is a liar. Manipulating
your resume to be more appealing
is valid, because it's not a liar.
Shifting keywords, re-ordering sections, highlighting specific experience: totally, 100% valid, and if you can automate that, a potential product (it's similar to stuff I banged on years and years ago). It's what people should be doing to their resume anyway.
Companies don't use AI against candidates, they use AI to try to weed through the tens, hundreds, or thousands of resumes they have to shuffle through to find maybe one or two standouts.
You wouldn't be using AI against a company, you'd be using it because (in your view) it's in your, and the company's, best interests to hire you. Guess what: lying and bullshitting to get a foot in the door does not demonstrate that, and only very rarely will it be positively received by the people you lied to.
If you're waiting for a "Ya' gotta lotta moxie, kid, yeeeaaaarrrrhh" you'll probably be waiting a long time.
