Do your CV and LinkedIn need to match?
Recruiters routinely open your LinkedIn while holding your CV. They are not checking whether the two documents are identical — they are checking whether both tell the same true story.
What must match
A different job title or shifted dates between the two documents is not tailoring — it reads as a credibility problem. And it usually happens by accident: people update one document and forget the other.
What may differ
Your CV should be tailored per job — different emphasis, reordered skills, deeper detail on the roles that matter for this application. Recruiters expect this; they do it with their own CVs.
LinkedIn is your stable public record; the CV is your targeted argument. Both can be true at once.
The gray zone
Claims on your CV with no trace on LinkedIn — a skill, a team size, a seniority signal — make recruiters wonder which version is accurate.
The fix is not weakening your CV. It is adding one honest line to LinkedIn that backs the claim.
