On Campus Interviews

[Vstressed]

So this is half questions and half venting tbh. The literature program I applied to invites a short lists of candidates to campus and admits people based off the interviews (and I'm assuming casual interactions) from that visit. So despite it being rather late, they haven't sent out any invitations.

Any advice on how to make a specific literary topic applicable to many professors? I talked about learning a minority language (that maybe two professors could help me with) in my statement of purpose, but I'm worried other professors will find it too niche. This is a comparative literature program btw. Do you think it should suggest doing another language as well as the minority language I discussed or would that look too flaky?

I also just got an email from the school inviting me to a Diversity day recruitment. It honestly made me so anxious, though, because it led with a "congratulations on your acceptance," but I haven't been accepted. It got me so riled up, and now I'm nervous about my interviews.  No responses needed on that really, I'm just upset that the generic email got my hopes up.
