What is an ATS and why does it matter for your job application?

An ATS (Applicant Tracking System) is software that employers use to filter resumes before a human ever reads them. Most mid-size and large companies use one. When you apply online, your resume goes into the ATS first.

The system scans it for relevant keywords, qualifications, and job titles. If your resume doesn't match enough criteria, it gets filtered out automatically. Around 75% of resumes never reach a hiring manager. That's not because the candidates are unqualified - it's because their resumes weren't optimised for the software reading them first.

What do ATS systems scan for in a resume?

ATS systems scan for specific keywords that match the job description. They look for job titles, technical skills, certifications, software names, and industry-specific terms. They also check for years of experience, education requirements, and location.

The system ranks your resume based on how closely your content matches what the employer asked for. Generic resumes score poorly because they don't mirror the language in the job ad. A project manager resume that doesn't mention "stakeholder management" when the job ad specifically asks for it will lose points every time.

How should you format a resume to pass ATS screening?

Keep it simple. Use standard section headings like "Work Experience", "Education", and "Skills". Avoid tables, text boxes, columns, headers, and footers - most ATS software can't read content inside them.

Stick to standard fonts like Arial, Calibri, or Times New Roman. Use bullet points for your achievements (the plain round ones, not fancy symbols). Don't use images or icons for contact details. Put your name and contact info in the main body of the document, not in a header. Save it as a .docx or a simple PDF.

Should you copy keywords from the job description into your resume?

Yes, but do it honestly. Use the exact phrases from the job ad where they genuinely apply to your experience. If the ad says "project coordination", don't write "coordinating projects" - use their exact wording.

Sprinkle keywords naturally through your work experience and skills sections. Don't stuff them into a hidden block of white text (ATS systems catch that, and it'll get you blacklisted). The goal is to reflect the employer's language while accurately describing what you've done. Match their words, back them up with real results.

Do ATS systems reject creative or designed resumes?

Often, yes. Fancy designs with graphics, icons, multi-column layouts, and custom fonts look great to humans but confuse ATS software. The system tries to parse your resume into structured data - name, job titles, dates, skills. When it hits a two-column layout or an infographic, it either scrambles the content or skips it entirely.

Save creative resumes for when you're handing them directly to someone. For online applications, submit a clean, single-column, text-based version. You can keep it polished without relying on design elements that break the parser.

What file format should you use for ATS - PDF or Word?

Word (.docx) is the safest choice for ATS compatibility. Every major ATS can parse Word files reliably. PDFs work with most modern systems, but older ATS software sometimes struggles to extract text from them - especially if the PDF was exported from a design tool like Canva or InDesign.

If the job ad specifies a format, use that. If it doesn't, go with .docx. Never submit a .pages, .jpg, or scanned document. If you prefer PDF, make sure you can select and copy the text in your file. If you can't highlight the text, the ATS can't read it either.
