Interview Validity for Selecting Sales Clerks

Interviewer judgments, gender, and age data were collected for job applicants interviewing for seasonal retail sales clerk positions in two separate years. Job performance data were matched with interviewer judgments for 312 employees in Year One and for 205 employees in Year Two. The correlation between interview judgments and job performance was .34 in Year One; after correction for criterion attenuation and restriction of range, the correlation was estimated at .42. The second year results yielded a correlation of .51, which, after corrections, was estimated at .61. Analyses of the data for differential prediction as a function of sex and age for both years revealed that females and older applicants received higher average interview evaluations, but regression lines did not differ significantly among the age and gender subgroups.
