Hey!
When I went to NOVA for my interview, two people did the actual interviewing. Treat the whole day as an interview though! We had lunch with Dr. Bacigalupi, who is the Assistant Dean of Student Affairs! And we are with the admissions people for tours and stuff all day!
And for @thisboy I submitted my OptomCas in early November, got a supplemental after a week, then interview request about 10 days after that. There is still time though!
