Rewriting a CV against an advert, and the line

Why tailoring works at all

Two companies with the same job describe it differently. One says “ETL”, one says “data pipelines”; one says “stakeholder management”, one says “working with the business”. A reader scanning for their own words does not find yours, and concludes you have not done the thing you have done for three years.

Tailoring is translation, and translation is honest. Everything in this lesson turns on the difference between saying a true thing in their vocabulary and claiming a thing that is not true.

A twenty-minute workflow

1. Extract the requirements. Paste the advert into a model and ask for each stated requirement as a separate line, with must-have and nice-to-have marked. Adverts bury this in prose and the list is clarifying.

2. Ask for a gap analysis against your CV. ”For each requirement, quote the line in my CV that evidences it, or say NOTHING FOUND.” You now have three piles: evidenced, evidenced-but-in-different-words, and missing.

3. Fix pile two yourself. This is the actual tailoring, and it is usually five or six lines. “Built and maintained nightly data pipelines” becomes “Built and maintained nightly ETL pipelines (data pipelines)” if both terms appear in their advert. One word, true, findable.

4. Rewrite the top third. The summary at the top of your CV and the first two bullets of your most recent role are the only parts most readers reach. Those get rewritten per application. The rest stays fixed. This is the eighty per cent of the value for twenty per cent of the work.

5. Decide about pile three. Missing requirements are a decision, not a writing problem. Missing one or two of eight is normal and you apply. Missing the central ones means the advert is describing somebody else and your hour is better spent elsewhere.

Do not let the model write the final text. It knows nothing about what you did, so anything it adds is either recycled from your own words or invented, and the second kind is what ends interviews.

The line, stated concretely

On the honest side: reordering bullets so the relevant work is first; using their term for a thing you did; adding a project you had left off; quantifying a result you produced; describing a team’s outcome and naming your part in it.

On the other side: listing a tool you have not used; changing a job title to one you were not given; moving dates to hide a gap; claiming a team result as your own work; converting six weeks of a course into “two years of experience”.

The reason to stay on the honest side is not only ethical, and it is worth being specific about the mechanism, because “you might get caught” is vague. You get caught in three predictable places. The technical screen, where twenty minutes of questions on the tool you listed goes badly in the first three. The project conversation, where “walk me through a hard decision on that” has no answer if you did not make it. And the reference or background check, where titles and dates are the two things that get verified, and a discrepancy is treated as dishonesty rather than as an error: offers are withdrawn for this, routinely, after acceptance.

There is a fourth cost people underestimate: an exaggerated CV wins you interviews for jobs you cannot do, and those interviews are miserable and consume the weeks you needed for the jobs you can do.

Gaps and career changes

You do not have to hide either. A gap gets one line, “2024–2025: caring for a family member; part-time study in data engineering”, and stops being a mystery. Interviewers ask about gaps because the silence invites the question, not because a gap disqualifies anybody.

For a career change, the top of the CV should say what you are now, with the previous career reframed as domain knowledge rather than apologised for. A nurse moving into health data has something that no computer science graduate has, and burying it is the mistake.

The limitation

Tailoring moves your response rate a few points. It is worth twenty minutes and not worth two hours, and it cannot rescue an application to a role you are three levels away from. If your funnel shows no first conversations, the fix is the route in, not another rewrite.
