Before a recruiter reads your resume, there's a good chance software reads it first. Applicant tracking systems (ATS) parse your resume into fields such as name, contact details, job titles, dates, skills and education, and recruiters search and filter on those fields. If the parser misreads your document, you can end up with a blank work history or a missing phone number in the employer's system, even if the resume looks great on screen.
The good news: an ATS-friendly format isn't complicated, and it doesn't have to be ugly. Here's what works, what breaks, and how to check yours.
What an ATS actually does with your resume
When you upload a resume, the ATS:
- Extracts the text from your file.
- Splits it into sections based on headings it recognizes (Experience, Education, Skills).
- Maps details into fields: employer, job title, start and end dates, school, degree.
- Stores the result so recruiters can search it ("project manager" + "PMP" + "Chicago"), and in many systems, compare it against the job posting.
Every formatting choice either helps or hurts one of those steps.
The ATS-friendly resume format checklist
Layout
- Use a single column. Two-column layouts can be read left-to-right across both columns, mixing your skills into your job history.
- Avoid tables and text boxes for core content. Many parsers skip text boxes entirely or read table cells out of order.
- Keep contact details in the main body, not in the page header or footer. Some systems ignore headers and footers.
- Skip icons, charts and skill bars. A five-dot "Excel proficiency" graphic means nothing to a parser, and it means very little to a recruiter either.
Headings
Use standard section names the software expects:
- Summary (or Professional Summary)
- Experience (or Work Experience)
- Education
- Skills
- Certifications
Creative headings like "Where I've Made an Impact" or "My Toolkit" look distinctive to a person but can confuse a parser trying to find your work history.
Fonts and formatting
- Stick to common fonts: Arial, Calibri, Garamond, Georgia, Helvetica or Times New Roman, at 10 to 12 point for body text.
- Bold, italics and simple bullets are fine. Unusual symbols as bullets (arrows, check marks, emoji) can come through as garbled characters.
- Use consistent date formats, such as "Mar 2022 – Present" or "03/2022 – Present," and use the same format everywhere.
File type
- .docx is the most reliably parsed format across ATS platforms.
- PDF is widely supported, as long as it's a text-based PDF exported from a word processor. A scanned or image-based PDF has no readable text at all.
- If the application says which format to use, use that one.
A quick test for a PDF: open it and try to highlight a line of text. If you can't select the words, an ATS can't read them either.
Chronological, functional or hybrid?
Reverse-chronological (most recent job first) is the safest choice for an ATS and the format most recruiters prefer. The software expects job titles paired with employers and dates, and this format gives it exactly that.
Functional resumes group experience by skill instead of by job. They can be harder for an ATS to map, because skills are separated from the jobs where you used them, and some recruiters read them as an attempt to hide gaps.
Hybrid (combination) resumes open with a short skills summary followed by a chronological work history. These work well for career changers, as long as the experience section still lists each job with title, employer and dates.

Keywords still matter, even with a perfect format
Format gets your resume read correctly. Keywords decide whether it gets found. Recruiters often search their ATS for specific job titles, tools and certifications, and many systems rank applicants against the posting.
- Mirror the exact names of tools and certifications from the job posting.
- Spell out acronyms at least once ("Certified Public Accountant (CPA)").
- Put your most relevant skills in both your Skills section and the bullets where you used them.

Common ATS format myths
"You need a plain-text resume with no formatting." No. Bold headings, bullets and clean spacing parse fine. The problems come from layout structures (columns, tables, text boxes, headers), not from basic formatting.
"ATS automatically rejects most resumes." Most systems are databases with search and ranking tools. Recruiters still make the decisions, but a resume that parses badly or doesn't match the search terms is much less likely to be seen.
"Hiding keywords in white text beats the system." The hidden text shows up in the parsed profile a recruiter sees, and it looks like an attempt to game the process.
How to check your resume's format
- Copy and paste test. Copy everything in your resume and paste it into a plain text editor. If the order is scrambled, sections are missing, or characters come through garbled, an ATS will likely have the same trouble.
- Highlight test (for PDFs). Make sure the text is selectable.
- Run an ATS scan. Get Hired Central's free ATS Scanner checks your resume against a job posting and flags formatting problems and missing keywords, so you can fix them before you apply.
The bottom line
An ATS-friendly resume uses one column, standard headings, common fonts, contact details in the body, and a .docx or text-based PDF file. Get those basics right and your experience arrives in the employer's system intact, so the content you worked on actually gets read. If you'd rather start from a clean layout, the Resume Builder produces ATS-friendly resumes in chronological, functional and hybrid formats.
