This year it seems like
1. the supply far exceeded the demand, esp on the behavioral side
2.a small number of candidates have most of the invites. Something like between 10 candidates, 30 schools are covered. Some years this happens, but rarely.
So it is a weird situation. These candidates likely will get multiple offers and good jobs, but 20 schools will end up not hiring someone by the end of November. Meanwhile the next 20 candidates will likely underplay because of this inefficiency.
