For dress code everyone was in business attire, because I only saw girls that day and I am myself one, all of them ended up wearing a pant suit and heels. But I’m sure for what you are wearing is perfect. The writing sample only asked one question and we had 30 min to do it, I think they changed it for every day (but it wasn’t nurse related for me) so it kinda threw me off. I was expecting a prompt that would ask like what is a nurses role, or how would you exceed in our program etc but it wasn’t like that.
