ATS killers to avoid
Each of these is documented to break parsing across major ATS platforms. Avoid them and your score climbs even without rewriting a single bullet.
- phone/email/location icons (SVG or Unicode) parse as garbled characters in Taleo and Workday; use plain | separators instead (competitor mistake seen on enhancv, resume.io templates)
- recommended by multiple competitors (enhancv, The Interview Guys) but causes left-column dropout in Taleo and Kronos; single-column is mandatory for this template
- ATS reads left column only or concatenates cells without spaces; use plain text list
- most ATS ignore header/footer entirely; all contact details must be in the document body
- Toolbox," "My Arsenal," "Technical Expertise" instead of "Skills"; ATS cannot map these to standard fields
- listing "EPA 608" alone without "Heating, Ventilation, Air Conditioning" full context elsewhere; ATS keyword matching requires the spelled-out form to appear at least once (in summary or job title)
- common in competitor templates for entry-level; for experienced techs this buries the EPA 608 credential below the fold, lowering its location weight
- some "career change" HVAC guides suggest leading with skills; ATS experience parsers require company → title → dates structure to extract work history correctly
