There are three commonly recognized resume formats, and choosing the right one for your specific situation matters more than most people realize - the wrong format can bury your strongest qualifications or draw attention to gaps you'd rather not highlight.
Chronological format (the default, and usually the right choice)
Lists work experience in reverse chronological order (most recent first), with education and skills as supporting sections. This is what most recruiters expect and what most ATS software parses most reliably.
Best for: a steady, relevant career history with no major gaps - which describes most job seekers, and is why this format should be your default unless you have a specific reason to deviate.
Functional format (organized by skill category, not job history)
Groups your experience under skill headings ("Project Management," "Data Analysis") rather than by employer and date, with a condensed work history section at the bottom.
Best for: almost no one, honestly. Many recruiters and most ATS parsers are less familiar with this structure, and it's often (correctly or not) associated with someone trying to obscure a spotty work history or a significant gap. If you're tempted to use this format specifically to hide something, a combination format usually serves you better.
Combination (or "hybrid") format
Leads with a skills or qualifications summary, then follows with a standard reverse-chronological work history. This gets you the best of both: a skills-forward opening for a reader skimming quickly, without abandoning the chronological structure ATS software parses best.
Best for: career changers who want to lead with transferable skills before a work history that doesn't obviously match the new field, and experienced professionals with a broad skill set they want to highlight before diving into role-by-role detail.
Which one should you actually use?
For most people, reverse-chronological. If you're changing careers and your most recent job title doesn't obviously signal fit for the role you want next, combination format lets you lead with relevant skills first. Functional format is rarely the right call - if you're considering it specifically to hide a gap, address the gap briefly and honestly instead (a short line noting a career break, further study, or caregiving is generally read better than an obviously reformatted resume trying to obscure it).
Formatting choices within any structure
Regardless of which of the three you choose, some formatting choices apply universally: single-column layout for reliable ATS parsing, standard section headers, consistent date formatting throughout, and a clean, readable font. See our ATS checklist for the full list.
Frequently asked questions
Can I mix formats within one resume? Combination format is essentially a deliberate mix by design. Beyond that, it's better to commit to one clear structure than to blend chronological and functional in a way that reads as inconsistent.
Does resume format affect ATS scoring? Yes, indirectly - a clean, standard chronological or combination format with a single-column layout parses more reliably than a heavily designed functional layout with unusual section groupings.
What format is best for someone with a large employment gap? Combination format, paired with a brief, honest line addressing the gap rather than a structure designed to obscure it entirely.
