I usually review the most recent ten to fifteen years of experience first, but I do not treat that range as a strict rule. I keep older work when it is unusually relevant, and I compress it when it provides context without current value.
I begin with relevance, not age
An older role may still matter if it proves industry knowledge, a required license, leadership experience, or a specialized skill the employer wants. A recent role may deserve less space if it is unrelated to the target.
I ask: does this experience help the reader understand why the candidate can perform the new role? If yes, I keep the useful part.
I give recent work more detail
The most recent positions usually receive the most bullets because they best represent the candidate’s current level. I describe older roles more briefly. This creates a natural sense of progression and keeps the document from becoming a complete autobiography.
I create an “Additional Experience” section
When earlier work matters but does not need full detail, I may use a compact section:
Additional Experience
Account Executive, Northline Media
Marketing Coordinator, Harbor Communications
I include dates if they are necessary for clarity and use the same general date style throughout. I do not remove dates selectively to manipulate the timeline.
I remove obsolete detail
Older software, routine duties, and outdated processes may no longer support the target role. I keep the underlying skill when it remains useful and remove the obsolete detail. For example, an old database name may matter less than the fact that the candidate managed data quality and reporting.
I handle long tenure carefully
If a candidate spent twenty years at one company, I show progression within that employer. I may list several roles under one company heading and give the most detail to the recent positions. This prevents the resume from looking static and shows increasing responsibility.
I think about age bias without distorting facts
I may omit graduation years when they are not required and not helpful, especially for degrees earned long ago. I do not remove employment dates from the recent work history. A confusing or incomplete timeline can create more concern than an honest one.
A practical example
A marketing candidate has a fifteen-year-old agency role in a regulated industry. The new employer specifically needs regulated-industry experience. I keep the old role, but I use one or two bullets focused on compliance review and client approvals. I do not give it the same space as the candidate’s current position.
My final decision rules
- I keep older work when it proves something the recent work does not.
- I shorten roles that repeat the same responsibilities.
- I give current work the strongest position and detail.
- I remove obsolete tools unless they add meaningful context.
- I keep the timeline clear and consistent.
I want the resume to show a relevant professional story, not every job ever held. The right cutoff is the point where older detail stops helping the target decision.
