Because of the lack of travel cost associated, I think more people are applying broadly compared to the past. my PD said our program got twice as many applications as previous years which may not sound like a ton saying that, but with every program normally getting around 50 applications for 2-3 spots and and giving out 24 interviews, places are getting 100-120 applications for the same number of spots and interviews.
for those not getting love right now, just be patient. i know it feels crappy when a bunch of people are getting interviews and you aren't. I know it doesn't mean a ton but I applied to 30 my year and only see 2 of the programs I applied to that sent out interviews thus far.
