A job that lasted four months, and what to do with it

Short roles are ordinary and people handle them badly in both directions. The decision depends on the gap it would leave.

— the gap it leaves is the whole question.

The rules count evidenced lines across roles. A short role with one good line still contributes to that.

Short roles are common and the advice about them is contradictory, because it is usually written as a rule rather than as a decision. There are three options and one question that chooses between them.

The question: what gap would it leave

The résumé builder's start step
Roles can be reordered, shortened or removed in the builder, and the document re-renders as you go.

Lay the dates out. If removing the role leaves no unexplained hole, leaving it out is a legitimate editorial choice about relevance. If removing it opens a gap of several months, the gap is more conspicuous than the role, and you have made the document harder to read rather than tidier.

Option one: keep it, with one line

Role, employer, dates, and one achievement line. That is enough for a reader to see what it was, and enough for the evidence-depth rule, which counts evidenced lines across roles rather than measuring tenure. Four months is long enough to have done one thing, and one thing is what the line says.

Option two: keep it as a single line

Role, employer and dates, with nothing underneath. Appropriate for a role that was genuinely brief and unremarkable, and for anything old enough that the detail no longer matters. The wider cut is in how far back a résumé should go.

Option three: leave it out

Reasonable when it was irrelevant and short enough to leave no visible gap, or when the role sits far enough back that you are summarising that period anyway. It stops being reasonable the moment it creates a hole somebody will ask about.

Contracts are a different category

A fixed-term contract that ran its course is not a short tenure, and marking it as a contract removes the question entirely. The same applies to seasonal and agency work, which is handled in freelance work on a résumé and in contractors and day rates.

What the scorer does about it

A Conxfolio ATS report on a well-evidenced document
Nothing in the report measures how long a role lasted. It measures evidence.

Nothing. The ATS checker measures extraction, the seven essentials and the four content rules, and none of them looks at tenure. What it will notice is a date format that changes halfway down the page, which costs 4 points, and shortened years, which cost 8. Date formats on a résumé is the fix.

A pattern of short roles

Different from one short role, and handled differently. Several brief positions in a row read as a history until you label them, and the label is usually accurate: contract, interim, agency, seasonal, fixed term. Marking them removes the question entirely, because a run of contracts is a career shape rather than a series of departures. What remains is the ordinary work of evidencing each one, and the useful habit is writing the line while the role is current, because four months of work is forgotten faster than four years.

What this page does not claim

That a short role is invisible to a reader, or that anybody minds. Some readers ask and some do not, and we have no data on which. What is claimed is about the document: a role that looks deliberate reads as an editorial decision, and one that looks apologetic invites the question it was hiding from. Writing it plainly, with dates, is the version that stops looking like a problem.

A related habit worth keeping if short roles are a pattern in your history. Write the one line for each while you still remember the work, rather than when you are applying. Four months produces one real achievement and it is forgotten within a year, which is how a career of contracts ends up looking empty on paper. The places to look afterwards are in evidence you forgot you had, and the shapes to write in are in when there is no number.

A final note about how much weight to give this decision. Less than it feels like. People spend an hour deciding whether a four-month role stays and five minutes on the achievement lines under a four-year one, which is the wrong allocation by a wide margin. Make the decision with the dates in front of you, write one line if it stays, and move on to the sections that carry most of what a reader will use.

Decide it with the dates in front of you

Roles can be reordered, shortened or removed, and the document re-renders as you go. The decision is reversible.

Questions

Should I leave a four-month job off
Only if removing it leaves no unexplained gap. The gap is usually more noticeable than the short role.
Does a short role hurt the score
No. The rules count evidenced lines across roles and do not measure tenure at all.
How much space should it get
One line of evidence, or a single role line with dates. It should look deliberate rather than apologetic.
What about a contract that was always short
Mark it as a contract or a fixed term. A twelve-month contract that ended on schedule is not a short tenure.
Do I have to explain why it ended
Not on the document. There is no field for it and a reader who wants to know will ask.
