I heard back from Michigan State on November 16th, inviting me for an interview there on December 8th. From what I could tell, they were conducting interviews all that week. Everyone interviewing on my day was from out-of-state; I don't know about those that they interviewed earlier in the week. Of those that they interviewed, Hilda (the director of admissions) said that they were going to try and inform the top 20-30% of their acceptances before Xmas. The rest that didn't hear back from MSU would still be considered against the remainder of the candidates that were going to be interviewed in February. I haven't heard anything yet, so my hopes are quickly going downhill about getting a nice Xmas present 🙁 . I hope you hear from them in the new year about an interview in Feb...
