I went to Purdue, and she is kind of like an administrator who knows nothing about ECE. She teaches seminars and stuff on networking and presentation skills and such. I would say it is a good sign, though I do not know why she would be the one to talk to you. Not to be rude but I hated this woman while I was there (but to be fair it was likely because she was often on panels grading presentations and would only ever comment on things like "well you said umm once, you need to work on that" and as a student who only cared about the subject matter, these kinds of comments always annoyed me). Anyone showing interest is a good thing, and I would not be surprised to find out that she refuses to sign off on any student she has not personally talked to.
