This study examines the extent to which highly structured job interviews are resistant to demographic similarity effects. The sample comprised nearly 20,000 applicants for a managerial‐level position in a large organization. Findings were unequivocal: Main effects of applicant gender and race were not associated with interviewers’ ratings of applicant performance nor was applicant–interviewer similarity with regard to gender and race. These findings address past inconsistencies in research on demographic similarity effects in employment interviews and demonstrate the value of using highly structured interviews to minimize the potential influence of applicant demographic characteristics on selection decisions.
