Not to be cheeky, but why did you apply to your list of programs in the first place? I mean, don’t you have reasons for each program?
For myself, I looked at location and selected programs in areas that I was already familiar with, or did extensive research into the area. I also dug deep into programs looking for anything I could find over what I might expect if I were in attendance. I read student handbooks, blog posts, personal websites, social media, newsletters, and so on.
I too have found that most students and faculty will stick to saying good things about the program, so why not ask them directly? It’s okay to ask if there is anything they don’t like about the program or a particular advisor. You can also ask what students do in their free time or what ECs they may be involved in. Doing so will also give you a good idea into the nature of the program.
