Use whichever resume will give you the best chance at securing the job. When applying, you have the option to select from different resumes. You can use:
Your saved resume
A new resume you upload specifically for the application
The resume used on your last application
Resume Rev resume
If I upload a new resume, will that replace the resume in my previous applications to roles?
No! If you upload a new resume, resumes attached to previous applications will not be updated and your previous applications will not be impacted.
