In SAP SuccessFactors Recruiting, interviewers' ratings for an applicant are displayed to recruiters in specific formats, including:
Average Rating for Each Competency (Option A):
In Interview Central, interviewers rate candidates based on defined competencies, and these ratings are averaged across all interviewers. This average score per competency gives recruiters an at-a-glance view of the candidate's performance.

Interviewers can also provide an overall recommendation, such as "Recommended" or "Not Recommended," which is displayed to recruiters, helping them assess whether the candidate is a good fit based on feedback from interviewers.
