Back when I was unsuccessfully applying to American medical schools, paper still ruled and the fact that I got an email from my home program rejecting me 6 months after I sent them my application (from the same city) was a source of puffed up ire for me.
Now, the fact that ERAS (and I imagine, AMCAS) has gotten everything into a neat package to be emailed around at whim is extremely convenient, and I do not miss paper in the slightest. That being said, the ease with which emails are sent leads to things like the the following:
-Rejection a week before the rank list was due.
-Predated invitation to a highly desirable and unlikely to interview me program sent the day after the rank list was due.
-Apology for fake emailed predated invitation.
-Interview rejection more than a week after Match Day! Slow clap, Colorado. Stay classy.
