Hiring teams are fluid, and as a BrightHire admin, you may not be able to invite every hiring manager and interviewers to create a BrightHire account before they need access.
You can avoid the need to manually invite new users by enabling self sign-up.
To do so, log in to your BrightHire account and navigate to Settings > General. There, you will see a section for User Sing-Up:
Toggle "Allow Self Sign-Up" to On, and enter your company's email domain.
Now, when a new user is directed to the BrightHire Sign-in Page, they will be able to use their GSuite / O365 credentials to sign in and create a new account at the same time.
