Oracle Taleo is the oldest and strictest major ATS. Single column, no images, no tables, standard section names, embedded fonts. Even modest deviations get the CV scrambled or dropped. Format right for Taleo and you've formatted right for every other ATS.
Taleo predates most modern parsing libraries. Its CV parser was built in the early 2000s and has only been incrementally updated since. The result: a parser that handles text from a single-column, plain-prose CV cleanly, and chokes on anything with visual flourish.
Major employers running Taleo include large enterprises in finance, healthcare, government, and Fortune 500 retail. If you're applying to a 10k+ employee organisation in those sectors, assume Taleo and format accordingly.
One, single column, end of story. Two, no tables, no text boxes, no floating elements. Three, standard section names: 'Summary', 'Experience', 'Education', 'Skills'. Four, dates as 'MM/YYYY to MM/YYYY' for each role; Taleo's date parser is finicky on year-only formats. Five, PDF with selectable text or plain text TXT; avoid DOCX with custom styles.
Taleo is one of the oldest and largest enterprise applicant tracking systems. Owned by Oracle, used by Fortune 500 employers in finance, healthcare, government, and retail. Its parser is the strictest among major ATS engines.
Taleo's parser was built in the early 2000s and has been incrementally updated since. It handles single-column plain prose cleanly and chokes on multi-column layouts, tables, text boxes, and embedded images. Re-export your CV as single-column PDF and the parse will land cleanly.
PDF with selectable text or plain text TXT. DOCX with custom styles can confuse Taleo's older parser. If you must submit DOCX, use the simplest possible Word styling.
Poorly. Taleo's parser reads top to bottom and scrambles column order. Use single column for any application going through Taleo.
MM/YYYY to MM/YYYY format works most reliably. Year-only ('2022 to 2024') is parsed less consistently. Always include both start and end dates per role.
Free check. The strictest parser in the industry.
