If I have this right, when you submit your secondary they will first review your letters to see if they fulfill the requirements. This may take a few weeks (and I think you'll be in "hold for information" status), then you reach complete status. From there, the committee reviews your application, and then designates you as eligible for interview (EFI) or not eligible for interview. If you are in EFI status, you may or may not be offered an interview. From earlier in the thread, I think about 30-40% of people in EFI status eventually get an interview, but it may not be right away and you may spend a few months in EFI status.
