Formule XYZ : écrire une expérience comme un résultat
A way of writing each line of a resume as "accomplished X, as measured by Y, by doing Z". **X** is the outcome you produced, not the task you were handed. **Y** is the number that proves it: a percentage, a lead time, a volume, against a starting point. **Z** is what you did to get there. For instance, "in charge of onboarding" becomes "raised first-week activation from 30% to 45% by rewriting the first three screens". Laszlo Bock, then head of people operations at Google, popularised the formula in a 2014 LinkedIn article. It is back in the prompts that hand resume rewriting to an AI: Cindy Zhu makes it the rewriting step of the agent chains she shares in two videos, one that diagnoses and rewrites a resume, another that tailors it to each job posting. The same loop shows up elsewhere in four moves: diagnose, compare, rewrite, prepare ([Instagram reel DdGm6h-TCL2](https://www.instagram.com/reel/DdGm6h-TCL2/)). Diagnosing means having the resume read the way an applicant tracking system (ATS) would and spotting the sections it misreads: columns, tables, made-up headings. Comparing means listing the skills and keywords the postings ask for that the resume lacks; the video promises a comparison against "1,000 similar job descriptions", but an assistant has no such corpus at hand, so give it the three or four postings you are actually targeting. Rewriting is the XYZ formula. Preparing means having the AI play the hiring manager, with the hardest technical questions for the role and a score out of ten on each answer: the score matters less than the question you stall on.
