the most recent interview invites were sent out for this coming weekend...april 20th and 21st..i'm not sure if they will be doing any more interviews..you might want to call them or email Dr. Wilcox
I spoke to Mo O'meara today and she confirmed that the interviews this weekend 20 & 21 April will be the last round. However, I don't want to held responsible for anything for make anyone feel :-( so u really should call to verify it.
