Upload your resume
Once connected, the panel asks for a resume if you haven’t uploaded one yet.- Supported formats: PDF and DOCX, up to 10MB.
- Matchr reads the file, extracts the text, and scores its formatting and content quality alongside every job match, so you’ll see both a match score and a sense of how ATS-friendly the resume itself is.
- You can upload more than one resume over time and switch which one is active without re-uploading, see Switching between resumes.
