Hi I'm in CNS track too and my interview was pretty straightforward. It was individual, not group. I heard some of my classmates got a board of 2-3 interviewers but I only had one person. It was at SON campus, real quick like 30 mins. It was mostly why u chose nursing, what's ur plan in 5 years, how u handled stress, to see any of your characteristics fits the track u applied for. I think it's more like a job interview tbh. So just be confident and remember to smile . Most of the interviewers are super nice! So u should be fine. Hope it helps!
