There are several advanced options available at the job posting level. To view these options, click + Show Advanced Options when creating or editing a job.

You can click on the On/Off toggle switches to make changes to any of these settings. These settings apply only to the job posting you are currently creating/editing. When you're done, click the Publish and Continue >> button at the bottom of the Edit Listing page.

Note: If both the "Allow Resume Uploads" and "Allow Cover Letter Uploads" toggles are set to Off, there will be no option on your application form for an applicant to attach a file. If either the "Allow Resume Uploads" or "Allow Cover Letter Uploads" toggles are set to On, applicants will be able to attach the file type(s) you enabled as well as an additional file upload feature. See the screenshot below to see what these options look like on a sample application form.

If want to require resume and/or cover letter uploads by default you can do this by going to Menu < Account Details < Applications.  These top-level toggles allow you to decide if resumes and cover letters should be allowed or required across all job applications instead of setting this setting for individual jobs. (Each of these toggles can be managed at the job level which will override these settings on a case-by-case basis.)
