Instead of an opinion, here is what Greenhouse, iCIMS and Workday say in their own documentation about resume files, and what USAJOBS says for federal jobs. Accepted types can vary by employer, so the upload box on the application has the final say. Whichever type you send, it should be a document with real, selectable text, not an image of one.
| System | Resume file types | Also documented | Source |
|---|---|---|---|
| Greenhouse | .doc, .docx, .pdf, .rtf and .txt | Its candidate FAQ says to upload a PDF for best results. | Greenhouse: supported formats Greenhouse: candidate FAQ |
| iCIMS | Varies by employer. Its candidate guide lists no file types. | Its developer documentation lists PDF, DOC, DOCX, ODT, RTF and TXT among the formats it can extract text from. | iCIMS: candidate guide iCIMS: developer docs, Binary Files |
| Workday | We found no single list of resume file types for career sites in Workday's documentation, so use a type the upload box lists. | Where an employer uses Workday HiredScore to grade applications, HiredScore supports DOC, DOCX, PDF, RTF and TXT resumes. | Workday HiredScore: candidate profiles |
| USAJOBS (federal jobs) | PDF, Word (DOC or DOCX), RTF, TXT, ODT and some image types, 5 MB or less. No PDF portfolio files. | Recommends a PDF to keep your formatting and number of pages. | USAJOBS Help Center: How do I write a resume for a federal job? |

Greenhouse's help center lists formatting its resume parser may not interpret correctly, and says these issues may leave a partial parse that someone has to correct by hand. The list includes:
Workday's documentation says parsing results can vary with a resume's format and the order of its words, and that resumes without images or image-based styles give the best results. Greenhouse adds that parsing can make mistakes, so review every field it fills in before you submit.
