I applied early action for Harvard and was deferred. I interviewed in November. What is strange is that I got an emailing requesting another interview in March. The way the worded it is weird and makes me think it means more than just the regular process:
The Harvard College admissions committee has been meeting for the past several months and will be making final decisions soon. (Name), Admissions Officer at Harvard College, has requested that fourteen Long Island students have a second interview on Saturday morning, March **, 2015 at location."
Everything is verbatim; I took out name date and location myself.
