How far back should a resume go?

The 10 to 15 year rule explained

Hiring managers and applicant tracking systems focus on recent, relevant experience. Work from 15 or more years ago is usually less relevant because tools, practices, and job titles have changed significantly. A software engineer listing a role from 2005 is describing a different industry. A marketing manager citing a campaign from 2008 is referencing a pre-social-media landscape.

The 10 to 15 year window is a guideline, not a hard rule. Use 10 years as your default. Stretch to 15 only when the older experience is directly relevant and you cannot make your case without it. Beyond 15 years, summarise rather than list in full.

When to go further back

Some situations justify including experience older than 15 years. The key test is whether the older role adds something the recent roles do not.

• You are applying for a senior or executive role and the older position shows a career arc that supports your current level.
• The older role is the only place you held a specific credential, licence, or skill the job requires.
• You work in a field where long track records matter, such as law, academia, medicine, or civil engineering.
• You are returning to a career after a break and your relevant experience predates the gap.
• The older role is at a well-known organisation and adds credibility that recent roles do not.

How to summarise older experience

Rather than listing every job from the 1990s or early 2000s in full, use a summary section at the bottom of your work history. This keeps the information available without giving it equal weight to recent roles.

A common format is a single line or short block labelled 'Earlier career' or 'Prior experience'. List the company name, your title, and the years. You do not need bullet points or achievements for these roles unless one detail is genuinely important.

Example: 'Earlier career: Sales Representative, Apex Distribution, 2003 to 2008. Account Manager, Redline Logistics, 1999 to 2003.' That is enough. If a recruiter wants more detail, they will ask.

How many jobs is too many?

Page length matters as much as years. A two-page resume is standard for most professionals with more than five years of experience. Three pages is acceptable for senior executives or academics with extensive publications. One page suits early-career candidates.

If applying the 10 to 15 year rule still leaves you with more than six or seven roles, cut the ones with the least relevance rather than the oldest ones automatically. A two-year role from 12 years ago that is directly relevant beats a four-year role from eight years ago that is not.

In the UK and Australia, a two-page CV is the norm. In Canada, two pages is standard for most roles. In the US, one page is sometimes expected for roles under five years of experience, but two pages is widely accepted for experienced candidates.

What to do with early-career or unrelated jobs

Jobs you held before your career took shape, such as retail work before you became an accountant, do not need to appear at all unless they are recent or fill a gap. Omitting them is not dishonest. A resume is a marketing document, not a sworn statement.

If you have a gap that the omitted roles would explain, address the gap briefly in your cover letter or in a short note in the resume itself. Do not leave a recruiter to guess.

• Omit unrelated early jobs if they add no relevant skills or context.
• Keep them if they explain a gap or show transferable skills the recent roles do not.
• If you include them, use the summary format rather than full bullet points.

Tailoring the cut-off to each application

The right cut-off point can shift depending on the job. A role that explicitly asks for 20 years of experience in a niche field may warrant going back further. A junior-to-mid role at a startup probably does not need anything beyond the last eight years.

Read the job posting carefully. If it lists specific past experience as a requirement, check whether your older roles satisfy it. If they do, include them. If the posting is silent on tenure, default to 10 to 15 years.

Break-In Bad's resume enhancement feature works through a conversation with Omar, who asks up to 20 questions about your background and helps you decide what to include, what to cut, and how to frame older experience so it supports rather than distracts from your application. She checks every line against what you have told her and keeps your original on file.

A quick checklist before you submit

Before sending your resume, run through these checks to make sure your work history is the right length and depth.

1. Does your resume cover the last 10 to 15 years by default?
2. Have you used the 'Earlier career' summary format for anything older?
3. Is the resume two pages or fewer for a non-executive role?
4. Have you removed unrelated early jobs that add no value?
5. Have you checked the job posting for any specific experience requirements that might justify going further back?
6. Does every role listed have at least one achievement or responsibility that is relevant to this specific job?
