Your account has a default setting that allows applicants to "Allow express applications from job boards." This means that when applicants click on your job posting on Indeed.com or ZipRecruiter and then click "Apply Now," they will be presented with a streamlined version of the application form. This simplified form only requests their resume and cover letter, bypassing any additional questions you may have included in the full application.
You can find this feature by using the Main Menu to select Account Details and then select Feature Managerment. Click here for step-by-step instructions.
