Examined behavioral styles used by interviewers to confirm their 1st impressions of job applicants. Three interviewers in a corporate setting formed 1st impressions based on application blank and test score information. They then conducted audiotaped interviews. Coders independently coded 79 interviews and found that 1st impressions were related to confirmatory behavior. Interviewers followed up positive 1st impressions, for example, by showing positive regard toward applicants, "selling" the company and giving job information, and gathering less information. Applicants' communication style and rapport with interviewers also differed. Significant differences in confirmatory behaviors also occurred among the 3 interviewers. A number of interviewer behaviors, especially positive regard, were related to applicant behavior in interviews. Although previous studies of expectancy confirmation have produced mixed results, the present results suggest that interviewers in natural settings do use confirmatory strategies, underscoring the importance of additional research on "self-fulfilling prophecies."
