This entire year has been an exercise in making things up as you go along. 6 months away from interview season, its a little early to say when exactly we are going to start interviewing. Even in normal years, we typically don't set our interview dates until 3 or 4 months before since that's when we have a better idea of which dates the Chair, PD, APDs and interviewing faculty will be in town. So to answer your question, it is almost certain things will start later. Especially for programs that normal kickoff their interview seasons in October. Others that typically start later might not be affected as much.
The main issue that is being discussed nationally are the number of applications we are all expecting to receive. There is a push from all residency programs to limit the number of applications/interviews on the student end. Because of the limiting factors of time, travel, and resources, most applicants can only attend 15-20 interviews at maximum. But this year, due to everything being virtual...there is little to stop a student from accepting 40+ interviews. Previous posters have touched on the affect this will have on rank lists and number of interviews offered per program.
If I may, I have questions for the forum. Especially to those of you who are in the application cycle or recently graduates. Given that everything is virtual this year, what sort of things can a program focus on that will properly address the things applicants want to see and learn? We know that it will be impossible to recreate the in-person experience. But what sort of virtual interactions will be most valuable to applicants? Would you rather have group sessions with existing residents? Or a series of one-on-one sessions? Is it worth it to produce a virtual tour? Or would you rather spend more time interacting with people in the department?
Once we get past virtual graduation (congratulations to all the seniors) and on-boarding of the new residents, we are going to substantive start planning for the fall. The collective wisdom of the group, either posted or written directly to me can only be helpful.
