ATS resume: what actually gets you past applicant tracking systems

What an ATS actually does

Greenhouse, Lever, Workday, iCIMS, Taleo and the rest are databases for applications. When you apply, the system extracts your name, contact details, work history, education and skills into fields. Recruiters then open the job, see a list of candidates, and either read them in order or search and filter: 'PMP', 'Toronto', 'React', 'eligible to work in the US'.

Some systems show a match score next to each candidate based on keyword overlap with the posting. Few companies auto-reject on that score; many recruiters sort by it when there are hundreds of applications. Knockout questions on the form ('Are you authorised to work in Canada?') are where automatic rejection usually happens.

The five things that decide whether a human reads it

1. You pass the knockout questions. Answer the authorisation, location and licence questions honestly and apply only where you pass them.
2. Your resume contains the posting's words for skills you actually have. If the posting says 'stakeholder management' and your resume says 'worked with partners', the search for 'stakeholder' misses you.
3. Your most recent role is relevant and clearly titled. Recruiters read the top third of the first page first.
4. The file parsed correctly. A single column, standard headings (Experience, Education, Skills), real text rather than text in images or tables, and a .docx or text-based PDF.
5. Dates and employers are unambiguous. Month and year for every role, the employer's real name, no overlapping jobs that look like errors.

Formatting myths you can ignore

• 'Only use Arial or Times New Roman.' Any common font parses fine. Avoid fonts that render as symbols.
• 'Never use a PDF.' Text-based PDFs parse well in modern systems. Scanned PDFs (images) do not.
• 'One page or you are rejected.' Length is a reader preference, not an ATS rule. Two pages for 8 or more years of experience is normal.
• 'Hidden white keywords beat the system.' Most systems render the text and recruiters see it; some flag it. It reads as cheating.

Formatting that really does cause problems

• Two-column layouts, where the parser reads across columns and jumbles your experience.
• Headers and footers containing your contact details, which some parsers skip.
• Skills in icons, charts or progress bars: the parser sees nothing.
• Creative section names ('My journey') instead of Experience, Education, Skills, Certifications.
• Tables for your work history.

How to match keywords without stuffing

Take the posting's required skills and tools. For each one you genuinely have, make sure it appears in your resume with the posting's wording, inside a real bullet that shows how you used it. Do not add a 'Keywords' block of unexplained terms; recruiters recognise it and interviews expose it.

This is the part worth automating. A tool that reads the posting, finds the overlap with your actual experience and rewords your bullets to match, per job, does in two minutes what takes thirty by hand. Break-In Bad's tailored resume does exactly this and asks you 'Have you done this?' for anything the posting wants that your resume does not show, so nothing is added that is not yours.
