Abstract: | This study evaluates the impact of the situational interview, personality measures, vocal attractiveness, and interactions between personality and vocal attractiveness on job performance. In a concurrent validity study with 154 customer service employees, a structured, situational interview was conducted and three of the Big Five personality factors (agreeableness, conscientiousness, and extraversion) are measured with two different frames‐of‐reference: at‐work and typical. Among the results are the validity of the situational interview and at‐work personality measures is established; vocal attractiveness correlates with both interview ratings and job performance; and finally, agreeableness and conscientiousness are found to vary in a pattern related to levels of vocal attractiveness such that both personality factors predict performance more strongly for people with more attractive voices. |
