Supplemental Video Application Invite?

From what I can gather, it seems to be unrelated to school interest or even application (i.e if you applied to any of these schools, you may be asked to submit your video interview to the others).

I just got a notification from Northwestern inviting me to complete this "optional" video interview. Is this whole thing optional or is it a application pool thinning tool? Thoughts?

To be honest, none of us have any clue what these mean, or if they're optional or not. I'm going to venture a guess that it's probably better to do them no matter what, and whether or not they put any weight on it remains to be seen. We're all in the same boat and this is the first year they are using it, from what I've heard. So good luck to everyone, hopefully it all works out for every one of us.

Seems appropriate
