LinkedIn profile vs. résumé: what should be the same, and what shouldn't

Sooner or later someone asks whether your LinkedIn should match your résumé. The short answer: the facts have to match, and almost everything else is allowed to differ. Most people get this backwards. They copy and paste the résumé into LinkedIn and call it done, or they let the two drift for years and hope nobody checks.

Somebody checks. A recruiter finds you on LinkedIn, opens your résumé, and puts the two side by side. A hiring manager does the same thing after the interview. If the dates or titles disagree, the question stops being "is this person a fit" and becomes "which one is true." That's a bad question to leave hanging.

I've changed industries three times, from heavy civil to project management to robotics, so I've rewritten both documents more than once. Here's how I think about which parts stay locked together and which parts should be different.

The facts: keep these identical

Some things are not matters of style. They're checkable, and anyone can check them. These should match exactly in both places:

• Employers and job titles. If your résumé says "Project Engineer" and your LinkedIn says "Senior Project Engineer," that's a mismatch a background check will flag, even if you meant nothing by it. Use the title you actually held.
• Dates. Start and end months, in the same format. A gap on one and not the other looks like you're hiding something, even when you aren't.
• Education. Degree, school, and year. If you didn't finish something, say so the same way in both places.
• Numbers. If your résumé says you cut a vendor contract from $160K to $86.1K, LinkedIn can't say $90K. Pick the real figure and use it everywhere.

A simple rule: if a fact would show up in a reference or background check, it lives in one source of truth, and both documents copy it. I keep a master version of my résumé for exactly this reason. It holds every role and number, and everything else is cut down from it. There's more on that in how a master résumé works.

What a résumé does that LinkedIn doesn't

A résumé is a targeted pitch for one job. You can reorder it, cut half of it, and rewrite the top of it to fit a specific posting. Nobody expects it to be complete, and the best ones aren't. A résumé that tries to hold your whole career usually ends up too long and says nothing in particular.

That's the job of tailoring: you take what's true and choose which true things to put first for this reader. I walk through that in how to tailor your résumé to a job description.

Your LinkedIn can't do that. It's one page that every reader sees, whether they came from a recruiter search, a friend's referral, or a job application. So it has to work for several readers at once instead of one.

What LinkedIn does that a résumé doesn't

LinkedIn is allowed to be longer, warmer, and more first-person. A few places where it should differ on purpose:

The summary reads like a person talking. A résumé summary is three tight lines pointed at one job. The LinkedIn "About" section can be a short paragraph in plain first person: what you do, what you're good at, what you're looking for. If you're changing fields, this is the place to say so out loud instead of making the reader work it out. If you want help with the résumé version, I wrote about how to write a résumé summary.

You can show more than one thread. A résumé aimed at a robotics job might leave out the earlier years of civil work to save room. On LinkedIn, those years can stay. Someone who found you through that earlier work is still a legitimate reader.

It carries the social proof. Recommendations, posts, projects, and the people you're connected to are all part of the profile. None of that fits on a résumé, and none of it should be copied there.

Bullets can be fewer and shorter. You don't need every accomplishment from every job. Two or three lines per role is plenty, with the strongest numbers up front. Anyone who wants the full detail will ask for the résumé.

The mistakes I see most

Copy-pasting the résumé into LinkedIn. It reads stiff there. Bullet-heavy text in a profile that's meant to feel human looks like a form someone filled in. Keep the facts, rewrite the voice.

Letting LinkedIn go stale. You updated the résumé last month for an application. LinkedIn still shows your job from two roles ago. If someone looks you up after you apply, they see the old story. Update both on the same day, even if the LinkedIn change is small.

Tailoring the profile too hard. A résumé can be pointed at one posting. A profile that's pointed at one posting looks odd to every other visitor. Aim it at the kind of role you want next, not one specific opening.

Different titles for the same job. Some companies use internal titles that mean little outside the building. It's fine to add a clarifying phrase on both documents, but do it the same way on both. Don't invent a more impressive title on one of them.

Forgetting your search is visible. If you're looking quietly while employed, a burst of profile edits can give it away. I covered how to handle that in confidential job search while employed.

A quick way to keep them in sync

Once you have a master résumé, the sync is easy, because the master is the single place where the facts live:

1. Update the master first, whenever something changes: a new role, a new number, a new certification.
2. Copy the changed facts into LinkedIn the same day. Titles, dates, and numbers are copied exactly. The wording around them can be your own.
3. When you tailor a résumé for a job, only the emphasis changes. Don't change any fact to fit a posting. If a tailored version says something the master doesn't, that's a problem to fix before you send it.
4. Every few months, open both and read them side by side, the way a recruiter would. It takes ten minutes.

This is how I use ResumAI. The master version sits in your vault, and each tailored version is cut from it for a specific job, so the facts don't drift between versions. It won't write your LinkedIn, and it won't make up a title or a number you don't have. It keeps your résumé versions consistent with each other, and you still have to do the LinkedIn half by hand.

The short version

• Titles, employers, dates, education, and numbers: identical in both places.
• Voice, length, and emphasis: different on purpose.
• Résumé: aimed at one job. LinkedIn: aimed at the kind of job you want next.
• Update both on the same day, and read them side by side every few months.

If I had to pick one habit out of all of that, it's the side-by-side read. Pull up both, pretend you're a stranger, and see whether they tell the same story. If they don't, fix the facts first and the wording second.

If you've got a mismatch you're not sure how to explain, or a pivot that doesn't fit neatly on either document, I'd be glad to hear how you handled it. What worked for you is the part I haven't figured out yet.
