just fyi, every single one of my interviews have been this way so far. And from speaking with fellow applicants during the interview day, it's been the same for them. I also wouldn't take comments like "we'd love to have you hear" to mean anything other than "you're a competitive applicant" which you should've known anyway since they invited you for an interview.
Long story short, and this is what I'm doing, go on your interviews, do your best, don't read into what they tell you or let it affect your rank list, rank the programs in the order of places you'd like to train, and hope for the best.
