How to tailor a résumé to a job description

Tailoring works. It is also the advice most often ignored, because "rewrite your résumé for every job" sounds like an hour per application. Done properly it is closer to fifteen minutes, and most of that is reading.

Read the posting twice, with different questions

First pass: what is this job actually for? Not the responsibilities list — the reason the role exists. A posting for a data analyst on a growth team is a different job from the same title in finance, and the résumé should know which.

Second pass: mark every noun that is a skill, tool or domain. Those are the terms a recruiter will search on and the terms a parser will index. You are looking for the ones you can honestly claim.

Change four things

1. 1.The summary, if you have one. Two lines that name the role you are applying for and the most relevant thing you have done.
2. 2.The order of bullets within each job. Most relevant first. This costs nothing and changes what gets read.
3. 3.The vocabulary of three or four bullets, so they use the posting's words for work you actually did.
4. 4.The skills section, so the terms that matter to this posting are present and the irrelevant ones are not crowding them out.

Leave employers, titles, dates and achievements alone. Those are facts. Tailoring is about emphasis and vocabulary, not about editing history — and a résumé that adjusts its facts per application will eventually contradict itself in an interview.

The vocabulary swap, concretely

"experience with A/B testing and experimentation frameworks"

Your bullet says:
Ran experiments on the checkout flow to improve conversion

Tailored:
Designed and ran A/B tests on the checkout flow, lifting
conversion 4.2% across 11 experiments

Same work, the posting's vocabulary, and a number. Nothing invented.

Keeping versions straight

The practical failure of tailoring is not the writing, it is losing track: three months later you cannot remember which version went to which company, and a recruiter refers to a bullet you no longer have.

Keep each tailored copy as a version rather than overwriting the original, and attach it to the application record. ORQILO does both — versions live alongside the résumé they came from, and the application tracker holds which one you sent where.

When not to bother

Tailoring has diminishing returns when you are applying at volume to near-identical roles. In that case build two or three strong variants for the role families you are targeting, and spend the saved time on the applications where you have a genuine edge — a referral, a domain match, a specific reason they should want you.
