The only thing you really need to bring is a pen. DCG gives you a folder with lots of school info and paperwork in it. I just jotted stuff down in there if I needed to. You'll see some people bring binders with notepads. It's totally up to you. You don't need to bring a resume.
get a portfolio folder with your resume, essays and paper and pen for notes.
Dress appropriately and relax.
Interviews are so chill now that I look back at it.
