Active applicants are those in any hiring Stage of your workflow other than Hired or Rejected.
Your applicant tracking system is designed to provide you with an overall view of applicants for the jobs to which you are assigned. You can review Applicant Files from Talent or any Job's Applicant Queue and apply custom filters to view active applicants, all applicants from any Stage, or limit applicants by selecting one or more specific Stages. Account Administrators have system-wide access to view all applicants from any job.
