Quick answer
Use a single-column reverse-chronological (or hybrid) resume with standard headings.
Most “ATS issues” are really parsing issues caused by layout tricks (columns, tables, text boxes, headers/footers, icons, images).
Two-resume strategy: Keep a “portal version” that is plain and parsable for ATS uploads. If you also want a designed PDF for networking, use it for direct email/LinkedIn—not for online portals.
What format is best for ATS?
For most roles, the safest ATS-friendly choice is reverse-chronological (most recent experience first). If you’re changing careers or have a non-linear path, a hybrid format can work—just don’t hide dates, employers, or job titles.

Chronological vs Functional vs Hybrid
1) Reverse-chronological (recommended)
- Structure: Contact → Summary → Experience (newest first) → Education → Skills/Certs
- Why it works: Parsers can reliably extract job titles, companies, and date ranges; recruiters expect this layout.
2) Functional (skill-based)
- ATS risk: Many systems struggle to infer years of experience when work history is de-emphasized or missing dates.
- When to use: Rarely for online portals. If you do, still include a clear Work Experience section with employers and dates.
3) Hybrid (skills + clear history)
- Structure: Summary + Key Skills (with proof) → Experience (chronological) → Education
- Pro tip: Put skills in context with achievements (not just a keyword list).
ATS-safe formatting rules (2026)
- Use one column: avoid columns and sidebars—reading order often scrambles.
- Skip layout tables: don’t use tables for Skills or headers; they’re a common parsing failure point.
- No header/footer contact info: keep name, email, phone, and links in the document body.
- Avoid text boxes / shapes / word art: floating elements can disappear or reorder.
- Keep it text-based: avoid image-only PDFs and heavy graphics/photos.
- Standard headings: use Summary, Experience, Education, Skills.
- Dates: use one consistent format (e.g., Jan 2023 – Mar 2025; Present for current role).
- Write titles fully: expand unclear abbreviations (e.g., “Senior Account Executive” vs “Sr. Account Exec”).
- Don’t space out letters: decorative spacing like N A M E can break word recognition.
- File type: if autofill scrambles your PDF, upload a clean
.docxversion (and re-test). - File size: keep it reasonable—some ATS parsers fail above limits (e.g., Greenhouse parsing fails above 2.5MB).

2 quick tests before you submit
- Plain-text paste test: Copy your resume into Notepad. If the order is scrambled or content is missing, simplify the layout (remove columns/tables/headers/text boxes).
- Autofill sanity check: After you upload, verify Work Experience fields (title/company/dates). Fix errors before submitting.
