LinkedIn About vs resume summary: same story, different documents
Your resume summary is three lines, tailored to one job, read by a screener in seconds; your LinkedIn About is up to 2,600 characters, aimed at everyone who ever looks you up, and written in first person. They must agree on the facts — role, level, specialty, direction — but they should never be copies: the resume version is the trailer cut for one audience, the About is the feature-length version for all of them.

A resume summary exists inside an application: the reader already has a job open, and the summary's only job is to declare your fit for that job in the first three lines. It is rewritten — or at least re-aimed — per application, in tight third-person-implied style ('Senior data engineer with 8 years building streaming platforms...').
The About section faces the opposite situation: you do not know who is reading or why. Recruiters vetting you, hiring managers pre-reading before an interview, prospects, former colleagues, conference organizers. So it speaks in first person, covers the durable story rather than one application's angle, and optimizes for the first three lines before LinkedIn's 'see more' fold — the profile's equivalent of the resume summary's three-line constraint.
The facts must be identical: titles, dates, level, core specialty, and the direction you claim to be heading. Screeners read both documents, and divergence — a resume claiming product management while the About still says project management — is the kind of mismatch that ends candidacies quietly. Run the comparison explicitly whenever you update either one.
The text should differ. Verbatim duplication wastes the About's extra room and reads as low-effort to anyone who sees both. The About can carry what the resume cannot afford: the through-line of your career, a sentence of motivation, the two problems you love solving, a list of specialties for keyword search, and a closing line telling readers how to engage. The resume summary compresses all of that to the three lines the target job cares about.
Write the About first, once or twice a year, as the canonical long version of your story. Then derive resume summaries from it per application: pull the sentences that match the job description, compress, convert to resume voice, and inject the JD's actual vocabulary. This direction — long canonical version, short derived versions — keeps everything consistent by construction.
When your story changes (promotion, pivot, relocation), update the About the same week and let the next resume derivation pick it up. The most common failure is drift: a resume rewritten fifteen times during a search while the About still describes the person from two jobs ago.
You can, but you are wasting the field — the About allows 2,600 characters and a first-person voice that can carry far more than a three-line summary. Keep the facts identical, expand the story, and let each document do its own job.
The About, as the canonical long version, updated once or twice a year. Resume summaries are then derived from it per application, compressed and re-aimed at each job description. That direction keeps the two consistent automatically.
Routinely. The profile is one click away from any application, and screeners use it to sanity-check dates, titles, and claims. Contradictions between the two documents raise questions that neither document alone would have raised.
