Setting up roles in Career Site Builder (CSB) is very important because many backend settings are available within CSB that should be accessible to trained admins only. Until you set up roles and permissions in CSB, all users with access to CSB have all permissions.
The consultant needs to talk with the customer about their organizational structure to determine how the roles and permissions will be configured and assigned. Only one role can be assigned per user, and users who access CSB from Command Center have all permissions.
