Persons seeking employment in any position shall file an application with the personnel director, who shall make those applications available to the appointing authority. The appointing authority, from time to time, shall conduct examinations to test the ability of such applicants. All qualified applicants shall be examined based upon factors pertinent to the ability to discharge the duties of the position. Examinations shall be practical and shall relate to those matters which test the ability of the person examined to discharge intelligently the duties of the position for which he or she applies. Once the qualified applicants have been examined, those selected for employment may then be hired by the appointing authority, as long as funding is available for the position. Any person may make reapplication for any position.
