A suitable testing method to evaluate friendliness and other attitudes would be a self-report inventory, where applicants can rate themselves on different dimensions such as friendliness.
Step-by-step explanation:
If you have chosen to evaluate applicants on attitudes like friendliness, a suitable testing method would be a self-report inventory. This type of test allows individuals to provide information about their own attitudes and behaviors through questionnaires or surveys.
