Know this is a little late, but might be helpful for next year...
Questions were hybrid between specific to this and MBA type questions.
Tell us about yourself.
Why Analytics? Why now? Why NC State?
Teamwork was emphasized: examples of working in a team, problems with a teammate, how would teammates describe you?
As far as program specific questions: Describe a linear regression to someone unfamiliar with math/stats (role-playing, think an exec that you are presenting data to). Some follow up questions there, also was asked to explain what a very simple regression was.
Good news here is that i somewhat botched this and was still admitted.
They also asked a spin on the weakness questions, which was what do you think will be your biggest challenge in the program.
Overall, there was a former student, the practicum head, admissions person, and a professor on the call. Nothing too out of the box.
