Maybe they are the exception to the rule, but the Fauci effect has been widely dismissed, with many people actually burning out and leaving healthcare since the start of the pandemic. In addition, while we do not have access to 2021-22 NJMS application data, since they do not publicly publish it like many other schools do, everyone who has reported has reported a significant decrease in applications as compared to last cycle, as apparently the chaos in the beginning of the pandemic merely served to push applications forward from future cycles, rather than significantly increasing the pool of future doctors.
If they are overloaded, it's because they are understaffed. Regardless of the reason why, they took your application fee and interviewed you. They are a rolling admissions school. Getting back to you by 2/28 will be great at this point, if it actually happens, but there is still no excuse to keep anyone waiting over 3 months post-II, without so much as a communication telling you that you are on hold, which is undoubtedly where you have been, since people who interviewed after you have already received decisions. JMHO, and good luck!!!
