How Far Back Should a Résumé Go? The Rule for 15, 20 and 30 Years of Experience

TL;DR: For most experienced professionals, a résumé should cover the last 10 to 15 years in detail. Earlier roles get one line each in an "Earlier experience" section, or nothing at all. Go further back only when the older work is the reason you're a fit. Graduation years are optional. Dates on the jobs you show are not. Two pages is normal for 15 or more years.

Key takeaways

• 10 to 15 years in full is the working rule. It's long enough to show your level and short enough for a recruiter to read.
• Condense, don't delete, when the early career matters: title and employer on one line, with or without dates.
• Go back further for a career change that returns to older experience, roles where a long track record is the point (executive and board searches), and academic or federal applications that ask for more.
• Graduation years are optional; the degree and school are not. The Age Discrimination in Employment Act protects applicants 40 and over, but bias still happens, so don't hand it a date it doesn't need.
• Never change dates to look younger or hide a gap. Leaving an old job off is editing; changing a date is misrepresentation.

The short answer: 10 to 15 years

A résumé is a pitch for one job, not a record of everything you've done. Recruiters read it quickly. In Ladders' eye-tracking study the average first screen took 7.4 seconds, and the résumés that did best opened with a short overview. In that time a reader is looking for three things: what you do now, how senior you are, and whether your recent results match the job.

The last 10 to 15 years answer all three. They show your current level, the tools and methods you use today, and results the reader can still check. Work from 20 years ago tells them less: technology, markets and titles have moved on, and an employer can't easily confirm it.

The range is a guide, not a cutoff. Use the shorter end if your recent roles are rich and closely matched to the posting, and the longer end if your most relevant work happened 12 or 14 years ago.

The rule at 15, 20 and 30 years

With about 15 years of experience, you can usually show everything. Give the most recent two or three roles full bullets, and your first role or two a line or two each. Don't cut a role just to make the résumé shorter if it shows how you got to your current level.

With about 20 years, the first five years are the ones to condense. Keep the last 15 in full, then add an "Earlier experience" line for the rest. The reader still sees a long career, without reading about your first job in detail.

With 30 years or more, the rule does most of the work. Fifteen years in full is already a two-page résumé at a senior level. Roles from the first half of your career become one line each or come off. If one of them holds a result you'd still lead with, move that result into your summary. Your career's length shows in the level you've reached, not in the number of jobs listed.

In each case, ask four questions of every older role: Is it relevant to this job? Does it hold a result I'd still lead with? Does the reader need it to understand my progression? Would I be glad to discuss it in an interview? Two or more yeses, keep it short. None, cut it.

Why the older years hurt more than they help

Long résumés don't fail because they're long. They fail because the important lines get buried.

• Your best recent result moves down the page. Every bullet about a 2004 role pushes a 2024 result further from the top.
• The reader does the math. A first job in 1992 tells them your age before they've read a single result.
• Old tools look like current skills. Listing software and methods you haven't used in a decade invites interview questions you'd rather not answer.
• Length signals a lack of editing. At a senior level, choosing what to leave out is part of the skill being judged.

None of this means your early career doesn't count. It means it should take up space in proportion to how much it matters for this job.

What to do with older experience

You have four options, from most to least visible.

1. Keep it in full (rarely)

Only when an older role is the strongest evidence for the job you want. A career changer returning to a field they left, or a candidate whose biggest relevant result is 16 years old, should show it with bullets. Everyone else should condense.

2. An "Earlier experience" section

List older roles as one line each, with no bullets:

Earlier experience: Plant Manager, Meridian Packaging · Director of Operations, Meridian Packaging

Dates are optional here. Include them if they make the progression clear and leave them off if they only add age. Either way, the reader sees a career that started earlier without reading about it.

3. Move one old result into your summary

If a single achievement from early in your career is still impressive and relevant, put it in your summary instead of keeping the whole role: "Took the network's lowest-performing plant to second place on cost per unit." The result travels; the date doesn't.

4. Leave it off

If an early job is unrelated to where you're going, such as a first career, a part-time role or an internship, cut it. It isn't dishonest. A résumé summarizes relevant experience. (Application forms that ask for complete history are different: answer those fully.)

When to go back further

The 15-year rule bends in a few situations:

• Career changers. If you're returning to a field you worked in earlier, that older experience is your evidence. Show it, and say in your summary why it's relevant. The career change guide covers how to frame a pivot.
• Executive and board searches. At the top, the arc of a career is part of the evidence: the turnaround you led 18 years ago may be why a board calls you. Keep the full progression, but give the oldest roles one line each.
• Long tenure at one employer. The typical US worker had been with their employer 4.1 years in January 2026. Workers aged 55 to 64 averaged 9.6, more than three times the 3.0 years for ages 25 to 34 (BLS). If you've been somewhere 18 years, show the titles you held there as a progression under one employer heading, even though it reaches past 15 years.
• Academic, medical and some government applications. A CV for academia or medicine is a complete record, and some public-sector applications ask for full history. Follow the posting's instructions over any rule of thumb.

Dates, graduation years and age

The Age Discrimination in Employment Act forbids discrimination against people who are 40 or older. That's the law. Bias still happens: in AARP's 2025 survey, 64% of workers 50 and older said they had seen or experienced age discrimination at work.

You can't control a reader's bias, but you can avoid giving them dates they don't need:

• Leave the graduation year off your degree if you graduated more than 15 years ago. "MBA, The Ohio State University" says everything that matters. Nobody will think it strange.
• Keep dates on every job you show in detail. Recruiters and applicant tracking systems use them to work out how long you've done the work, and a missing date looks like you're hiding something. Use one format throughout, such as "Mar 2019 – Present".
• Don't change dates or merge jobs to look younger or cover a gap. It is the kind of thing that ends an offer at the background check. The career gap guide covers gaps honestly.
• Lead with recent results and current tools. The best answer to an assumption about age is evidence that you're doing current work now.

What it looks like: a 20-year résumé

Our executive résumé example shows the rule in practice. The sample candidate, a COO with more than 20 years in operations, is fictional:

• The last 16 years in full: three roles from Vice President, Supply Chain to Chief Operating Officer, each with results: an EBITDA margin up from 8.1% to 11.3%, $18M in Lean savings, two acquisitions integrated. The oldest of the three is just past the 15-year mark, but supply chain is half of what the COO posting asks for, so it stays.
• 2002 to 2009 condensed: Director of Operations and Plant Manager at an earlier employer, one bullet each.
• No graduation years on either degree.
• Two pages, with the strongest results on page one.

When we tailored that résumé to a COO posting with OneResume, the engine kept the two oldest roles to one bullet each and put the P&L, EBITDA and acquisition results the posting asked for into the summary.

How long should it be?

With 15 or more years of relevant experience, two pages is normal. One page forces you to cut results a senior reader wants to see. Three pages usually means the older years haven't been condensed. Executives and academics sometimes go longer, but put the strongest work on page one, because page three rarely gets read.

If you're well over two pages, cut in this order:

1. Bullets on roles older than 15 years.
2. Duties that don't have a result attached.
3. Skills and tools you no longer use.
4. Repeated results (if three roles say "cut costs", keep the biggest).

LinkedIn is different

Your LinkedIn profile isn't a pitch for one job, so it can go back further. Older roles can stay with a line or two each. Keep the headline and About section focused on what you do now and want next. Those are what recruiters read first. Our LinkedIn headline generator helps with the headline, and the LinkedIn profile checklist with the rest.

A checklist before you send it

• The last 10 to 15 years are shown in full, with a result in most bullets.
• Older roles are one line each, or gone.
• Every job shown in detail has dates in the same format.
• Graduation years are off if they're more than 15 years old.
• Skills and tools are ones you use now.
• Two pages or less, with the best work on page one.
• Your summary names what you do now and the job you want next.
