The Influence of the In-person Residency Interview: A Prospective Study.

Abstract

This prospective study investigated whether in-person interviews affected interviewer assessments of anesthesiology residency applicants at an academic medical center, and which applicant characteristics influenced interview performance. Eighteen faculty members involved in residency recruitment between November 2019 and January 2020 documented preinterview (after full application review) and postinterview scores of the applicants on a scale of 1 to 5. Faculty also reported the relative contributions of specific interview characteristics (personality, physical appearance, professional demeanor, discussion regarding academic/scholarly activity, and level of interest in the specialty) to their postinterview assessments. Mixed-effects models were used to assess whether interviews changed faculty assessment of applicants, and what the relative contributions of applicant characteristics were to faculty assessments. A total of 696 interviews were conducted with 232 applicants. The postinterview scores differed significantly from the preinterview scores (estimated mean difference, 0.09 ± 0.02; P < 0.0001). The characteristics most affecting postinterview scores were positive impressions of applicants' personalities (marginal mean change in postinterview score, 0.259; 95% confidence interval, 0.221-0.297) and negative impressions of applicants' professional demeanor (marginal mean change, -0.257; 95% confidence interval, -0.350 to -0.164). In-person interviews significantly affected residency applicants' scores. Personality and professional demeanor influenced scores more than did other characteristics examined. Further studies are needed to clarify the relevance of in-person interviews to the assessment of residency applicants.
