Resume Format
The structural layout of your resume — chronological, functional, or combination. Format determines how your experience is organized and how easily an ATS can parse your information. Chronological is the default for most candidates.
Resume format refers to how your work history and skills are organized on the page. Three main formats exist: **Chronological** lists work experience in reverse order (most recent first). It's the most familiar to recruiters and easiest for ATS to parse. Use this for 95% of applications. **Functional** groups skills and accomplishments by theme rather than by employer. It was designed to hide employment gaps or frequent job changes, but modern recruiters recognize it immediately and view it with skepticism. Most ATS systems struggle to parse it correctly. **Combination (hybrid)** puts a prominent skills section at the top followed by chronological work history. It works well for career changers who want to lead with transferable skills while still showing a clear work timeline. Beyond structure, format also refers to file format: PDF vs. DOCX. PDFs preserve your visual formatting across devices, but some older ATS systems (Workday in particular) parse DOCX more reliably. When in doubt, submit PDF unless the application explicitly requests Word format. Visual formatting — margins, font size, column layout — affects readability for human reviewers. Single-column layouts are most ATS-safe; clean two-column layouts can work in modern systems.
Why it matters
Choosing the wrong format can torpedo an otherwise strong application — functional resumes raise red flags with recruiters, and format choices that break ATS parsing mean your application never reaches a human. Format is the container; get it right so your content can do its job.
Candidate tip
Default to reverse-chronological format with standard section headings (Work Experience, Education, Skills) and submit as PDF unless the job posting requests otherwise.
