Purpose: Each year, medical students go through the residency application process and are faced with the decision of where to apply. If they receive an interview offer at an institution, they are faced with another decision, when to schedule their interview. Studies have examined the possible effect of interview date on matching and on match rank. However, other variables such as examination scores, letters of recommendation, and class rank also effect match outcome. There have been no studies investigating the possible role the time of day in which the interview takes place can affect the residency interview process. The purpose of this study is to investigate the effect of date and time of day on interview score.

Methods: Data for the interview cycles of 2016-2017, 2018-2019, and 2019-2020 at a PGY1-3 ACGME-accredited EM residency program in Philadelphia was obtained. A linear regression analysis was done using the date, time, and score of the residency interviews. The regression was analyzed for a statistically significant relationship between the date and time of the interview and the interview score.

Results and Conclusions: There were no statistically significant differences found between the interview scores that occurred at different dates and times of day. These results align with those of similar studies. This should assure residency applicants that the interview process is working correctly and extraneous variables outside of their applications will not play a role in the match process
