Internal Applications refer to cases where a Talent Scout applied to a job in Radancy Employee Referrals.
If internal applications have been enabled by your Company Admin in the Account Preferences, you will find the option "I would like to apply myself" at the end of the job description.
Please note: in the case of an internal application, the recruiter assigned to the job will be automatically assigned as the referrer and will receive points if the Referral results in a successful hire.
