Sorry. If you are on hold for more than 2 weeks, I wouldn't count on an interview invite. They have tons of applicants. Check last years thread.
edit: this was on last years thread
"This is pretty interesting, and I hadn't even though about it until I read the posts about the various statuses. My status says: "Your file is complete and pending further review by our Committee on Admissions. If you are granted an interview you will be contacted by phone and/or email. Our interview season is September thru April and your file can be reviewed several times during this time."
I called the admissions office to see if they could add a little clarification to what this means, and the woman told me that my application has already been reviewed once and is now "set aside" to be re-reviewed later in the cycle. She wasn't very precise on when the second review happens, but she did mention it might not be considered again until later this winter/spring. As far as the "has been reviewed" statuses... I'm not exactly sure what that means. From browsing through last year's thread it looks as though it means that once the "has been reviewed" status appears, you are no longer under consideration for an interview invite from the committee. Obviously, SDN is a small sample size of the applicant pool, and that is just a bit of speculation. I thought those that have the same status as me would appreciate knowing what's going on with their application, though. Good luck through the rest of the cycle!"
they also said you have a better shot at getting an interview if you never get the hold status and it says your application is complete.
I know its not good news for some people, but I absolutely hated being on hold for 8 months
