Interviews: Some, all or none of the applicants may be interviewed. As a part of the Federal-Wide Hiring Reform Initiative (streamlining the hiring process), the FAA is committed to eliminating the use of the Knowledge, Skills and Ability (KSA) narratives from the initial application in the hiring process for all announcements. Therefore, as an applicant for this announcement, you are NOT required to provide a narrative response in the text box listed below each KSA. In lieu of providing a KSA narrative response in the text box listed below each Leadership and Management Dimensions, in your work history, please include information that provides specific examples of how you meet the response level or answer you chose for each KSA. Your work history examples should be specific and clearly reflect the highest level of ability. Your KSA answers will be evaluated further to validate whether the level that you selected is appropriate based on the work history and experience you provided. Your answers may be adjusted by a Human Resource Specialist as appropriate. Eligible applicants meeting the minimum qualification requirements and selective factor(s), if applicable, may be further evaluated on the Leadership and Management Dimensions listed in the announcement. Based on this evaluation, applicants will be placed in one of the following categories: score order, category grouping, or alphabetical and referred to the selecting official for consideration.
