This is where I am, too. Today is a "why am I doing this I'm not good enough" day. And I'm switching fields too, so I'm imagining committees looking at my app and being like, why is this person even applying she's never taken any epi classes!"
Interview did not go as well as I thought. No in person invite. I can pinpoint at least three things I could've done better but ugh. I'm not prepared for yet another round of rejection.
Also @DBear let me know if you're headed to Philly!! I applied to Penn too and I actually used to work at Temple. It's a pretty fun city!
