The short answer
Use reverse-chronological unless you have a specific reason not to. The combination format is the right answer for career changers. The purely functional format is a recognised red flag and should be avoided almost always.
What matters most
- Reverse-chronological is the default and the right answer for roughly nine candidates out of ten.
- Functional resumes hide dates, and experienced recruiters read that as concealment.
- The combination format gets you the benefit people want from functional, without the suspicion.
- Applicant tracking systems parse chronological structure most reliably, because it is what they were built for.
The three formats at a glance
| Format | Organised by | Best for | Main risk |
|---|---|---|---|
| Reverse-chronological | Jobs, newest first | Almost everyone with a reasonably continuous work history | Makes gaps and short tenures visible |
| Functional / skills-based | Skill groups, with employment reduced to a bare list | Very few people — see the narrow cases below | Widely read as hiding something; parses badly |
| Combination / hybrid | A skills or qualifications block first, then full dated jobs | Career changers, returners, consultants, people with wide-ranging histories | Runs long if the skills block duplicates the experience |
Reverse-chronological: the default
This is the format almost every resume you have ever seen uses. Contact details, summary, then employment listed newest first with dates, employers and achievement bullets, then education, then skills and certifications.
It is the default for a reason that has nothing to do with tradition: it answers the reader's actual questions in the order they ask them. What are you doing now, how long have you been doing it, what did you do before, does the trajectory make sense. A recruiter can assess fit in about fifteen seconds because they already know where everything is.
It is also the structure applicant tracking systems were designed around. Parsers look for a repeating pattern of title, employer and date range in order to build an employment record. When you give them exactly that, extraction is close to perfect. When you scatter your achievements into thematic buckets and list employers separately, the parser frequently fails to associate any experience with any job, and the profile it builds of you looks thin even though your document is full.
Functional: what it promises and why it backfires
A functional resume replaces the job-by-job history with themed skill sections — "Project Management", "Client Relations", "Technical Skills" — each containing achievements pulled from anywhere in your career. Employment appears at the bottom, if at all, often as a list of company names with no dates.
The promise is obvious. If your relevant experience is scattered across a decade, or sits five years back, or came from volunteering rather than a job, this format lets you lead with the material that helps you. That is a real problem and the impulse is reasonable.
The reason it backfires is equally simple: recruiters have seen it before. A resume with no dates attached to any accomplishment is, in the experience of anyone who screens applications, most often sent by someone with a gap, a very short tenure or a mismatch they would rather not lead with. The format itself now carries that signal, which means it announces exactly the thing it was chosen to soften. And because the reader cannot tell whether an achievement is from last year or from 2013, every claim gets discounted.
There is a second, more mechanical problem. A skills-grouped document gives a parser nothing to anchor on. Many systems will list you as having no employment history, and a recruiter filtering on "5+ years in current field" simply will not see you in the results.
Combination: the one most people actually want
The combination format opens with a summary and a substantial qualifications or core-skills block — typically six to ten lines that make the case for your fit directly — and then presents a completely normal, fully dated reverse-chronological employment history underneath.
You get to lead with relevance. The reader gets the dates. The parser gets its title-employer-date pattern. Nothing is hidden, and the argument for your candidacy is made before the history that might otherwise raise a question.
How to build the opening block
- Pick four to six themes that mirror the language of the posting — not generic ones. If the posting says "stakeholder management", use that phrase rather than "communication".
- Under each, put one concrete line of evidence with a number in it, and name where it happened. "Stakeholder management — ran the monthly steering group for a £4M programme across four departments (Brightwater, 2023–25)."
- Keep the whole block to roughly a third of page one. Beyond that it becomes a second resume stapled to the first.
- Do not repeat those same lines verbatim in the experience section. Reference them there in a different form or use different achievements, otherwise the reader feels they are reading the same document twice.
This is the format we would recommend to almost anyone whose instinct was to go functional. It is also what most good career change resumes look like when they work.
Choosing yours
Work through these in order and take the first one that describes you.
- 1Is your current or most recent job relevant to the target role?
If yes, and your history is broadly continuous — reverse-chronological. This is where most people stop.
- 2Is your relevant experience real but not most recent?
Combination. Lead with a qualifications block that surfaces it, then let the dated history sit underneath doing its job.
- 3Are you changing fields entirely?
Combination, with the opening block built around transferable evidence and any new training or projects, and the old roles described in the vocabulary of the new field.
- 4Do you have a gap of a year or more?
Still reverse-chronological. Address the gap directly rather than restructuring the whole document around avoiding it — that is a smaller problem than it feels like, and there is a way to handle it.
- 5Is your history genuinely a list of dozens of short engagements?
Group them. One entry for "Freelance developer, 2019–2026" with selected named clients as sub-bullets is chronological, honest and readable.
Gaps, short tenures and the format temptation
Almost everyone who seriously considers abandoning the chronological format is doing so because of a gap or a run of short jobs. It is worth confronting that directly, because restructuring the whole document is an expensive answer to a problem that has a cheap one.
A gap of a few months is invisible if you use years rather than months, and unremarkable even if you do not — hiring managers have lived through the same decade you have. A gap of a year or more is better handled by naming it than by hiding it: a dated entry reading "Career break — full-time caring responsibility, 2023–2024" occupies one line, closes the question, and reads as confidence. The alternative, an unexplained hole, invites the reader to imagine something worse than the truth almost every time.
Short tenures are the harder case, and the honest tactic is grouping rather than concealment. Three six-month contracts through the same agency belong in one entry with the agency as the employer and the placements as sub-bullets. Consecutive roles at the same company belong in one entry with the titles listed beneath, which turns what looked like churn into visible progression. Neither of these hides anything; both stop a reader's eye registering a pattern that is not really there.
What none of this requires is a functional resume. The gap is a two-line problem and the format change is a whole-document decision with a real cost attached, which is why it so rarely turns out to be the right trade.
Format is not the same as layout
One distinction worth being precise about, because the words get used interchangeably. Format is how the information is organised — the three options above. Layout is how it is presented visually: one column or two, where the headings sit, what the accent colour is, which typeface it uses.
They interact in exactly one place worth knowing about. Two-column layouts can confuse older parsers, which occasionally read straight across the page and interleave the two columns into nonsense. Most modern systems handle it, but if you are applying through a large corporate careers portal and cannot tell what is behind it, a single-column layout removes the risk entirely at essentially no cost. Every template marked ATS-safe in our template gallery is single-column for this reason.
The related question — whether to send a PDF or a Word file — is worth settling too. Send a PDF unless the application form explicitly asks for .doc or .docx, because a PDF preserves your layout everywhere while a Word file can reflow on someone else's machine. Modern systems read PDFs perfectly well; the advice against them is about a decade out of date.
Section order within a chronological resume
Choosing reverse-chronological still leaves you a decision about the order of the blocks underneath it, and that order is not fixed by convention as tightly as people assume.
| Order | Suits |
|---|---|
| Summary → Experience → Education → Skills | The default. Anyone with three or more years of relevant work. |
| Summary → Skills → Experience → Education | Technical roles where the stack is a hard filter, and anyone applying through a keyword-heavy portal. |
| Summary → Education → Projects → Experience | Students and graduates within about two years of finishing. |
| Summary → Credentials → Experience → Education | Regulated professions where a licence or registration gates the application. |
The one ordering rule worth treating as fixed: employment dates should be findable without effort, in the same position on every entry. A reader checking continuity is looking at a single vertical strip of the page, and anything that breaks that alignment — dates on the left for one job and the right for another, or a job where the date sits under the bullets — makes a routine check into work.
What about a two-column sidebar?
A narrow sidebar holding contact details, skills and certifications, with experience in the wide column, is a layout rather than a format, and it is fine for direct applications. The thing to avoid is putting anything load-bearing in it — your employment history, your dates, your summary. If a parser drops the sidebar entirely, which occasionally happens, the remaining document should still be a complete and coherent resume. That is a good test to apply to any decorative layout: delete the pretty part mentally and see whether what is left still does the job.
Two things no format can fix
It is worth being blunt about the limits here, because format choice attracts more anxiety than it deserves. No arrangement of sections will make an unqualified application succeed, and no arrangement will hide a fact that a reference check or an interview will surface in the first ten minutes.
What format does is control what gets found in the fifteen seconds you are given. That is genuinely valuable and worth getting right, and it is also the whole of the benefit. Once the structure is sound, every further improvement comes from the content — better evidence, sharper numbers, closer alignment with the posting. Run the finished document through the ATS checker to see how it parses and what terminology it is missing, then spend your remaining time on the bullets rather than on the skeleton.
Questions people actually ask
Which resume format do employers prefer?
Reverse-chronological, by a wide margin. It is what recruiters are trained on, what applicant tracking systems parse most reliably, and what makes a career trajectory readable in seconds. Deviating from it should be a deliberate decision with a specific reason behind it.
Are functional resumes automatically rejected?
Not automatically, but they are treated with more scepticism than any other format, and they parse poorly enough that a filtered search may never surface them. If your reason for wanting one is that your relevant experience is not recent, the combination format solves that problem without the cost.
Is a hybrid resume the same as a combination resume?
Yes. Hybrid, combination and occasionally "skills-first chronological" all describe the same structure: a substantive qualifications block up top, followed by a fully dated employment history.
Should I use a one-column or two-column layout?
One column is the safer choice for large corporate application portals, because a minority of older parsers mishandle columns. Two columns are fine for direct applications, smaller employers and any situation where a person opens the file. The content matters far more than the column count.
Does the format change for a CV?
A UK or European CV for ordinary job applications uses the same reverse-chronological structure. An academic CV has its own conventions entirely — sections for publications, funding, teaching and service, each in its own chronology — and is not really one of these three formats at all.
