i really don't know. widener has four interview days that they posted on their website. i assumed they do it in groups. like the first group is for those who have the best credentials, second group for next best, etc. i could be wrong, but thats what i thought. either way, i don't care, as long as they invited me for an interview!! i wouldn't care if it was on their fourth date! i'm just thrilled to be invited 🙂
Congrats on your interview! I actually don't think the interviews are ranked as you suggested, based on the fact that the first round of Widener invites went out a full week before the application deadline. So I think (I could be totally wrong) that all of the groups they invite are equally qualified, and it's all just a matter of when they actually look at your application that determines when you get an interview. Here's hoping we both get in!
