Duke (for pharmacology) was actually my favorite for a while, especially after the interview. My student host was really nice and was willing to set up a Zoom call to talk about the program, the faculty were easy to talk to and had research interests similar to mine, and their career development program seems fantastic. A faculty member who I didn't even interview with reached out to say congrats, that he also went to undergrad where I did and was happy I did well there, and to reach out if I had any questions. Overall, they made me feel really welcome.
Penn is similar in the sense that I am very interested in the research there, my student host was amazing, and I actually enjoyed the interviews. I think both would be really good fits for me, but because my boyfriend got into a medical school in Philly, and none in North Carolina, Penn ultimately has the edge. I totally understand not feeling a connection with a program though - everyone keeps saying to trust your "gut feeling" on schools, and there were some interviews that were just more tiring than exciting. It's harder to get a feel through Zoom, but I think those initial intuitions are still valid and very important.
