The strongest edits are usually selective
Most of the time, the biggest gains come from changing the summary, the order of bullet points, and the wording of relevant achievements. You usually do not need to rewrite the entire resume.
Examples
Resume tailoring examples are useful when they show what actually changes.
The best examples do not just show two finished resumes. They show how the same candidate shifts emphasis from one job target to another so the logic becomes obvious.
Examples should teach prioritization
A useful example makes it clear why one project moved up, why another bullet was shortened, and why specific terminology was chosen for that role.
The same logic applies to a CV
International applicants using the term CV still benefit from the same discipline: read the brief, match the signal, and make the fit obvious quickly.
