Here you go, very informative, somebody posted from last year
It seems like there are 4 levels of status updates:
1. "The committees file review indicates that they are very interested in your candidacy. We are trying to get all candidates at your priority score interviews as soon as possible IF we have an adequate number of interview slots."
2. "The committee's file review indicates that they are interested in your candidacy. However, due to the increase in the applicant pool this year, it is clear we MAY be unable to interview all the candidates at your priority score. If we do find that we are unable to grant an interview, you will be notified by e-mail in March."
3. "The committee's file review indicates that they wish to consider your file over the next several weeks before making a decision about interview. Your file will be reviewed again by a small sub-committee before making a final decision. Once a decision has been made on your profile, you will receive an email regarding your recent status update."
4. "The committee's file review indicates that they would like to consider your file further. We are now in the process of scheduling interviews and will continue to do so through February. Unfortunately, the committee indicates interest in far more candidates than we are able to interview. Since we are dependent on the Committee member's schedules for interview spaces, we are unable to predict when or if we will be able to schedule you this year. If your status changes, you will receive an email regarding your recent status update."
