Not explicitly, as far as I can remember. From their website, just about every faculty member is taking at least one person, so I think 6? In-person the director mentioned they typically take between 5-7. The first-year cohort there now has 5. Have fun at the interview! It was a good experience.
Just interviewed at UMSL. They told us they received approximately 175 applications (IIRC) this year and are interviewing less than 40. - I would assume that's how many accepted interivews; not sure how many they extended or if that's actually how many. Their first interview day was Monday (1/28) and their next is this weekend.
Have not received invitation for in-person interview to UNC; as others have indicated, as far as I know these invitations will not be extended until after the holidays.
Had Skype interview with clinical POI two weeks ago. Was told would it will *most likely* be after holidays before in-person invites are sent. Hope this helps.
