I brought a bag that could fit a portfolio and a small notebook. I had my resume and school-specific essay printed out, which I thought was a little extra but it helped me *feel* prepared to review them beforehand in case they decided to address specific things that I wrote. Same with mcs1225 with the phone, wallet, mints, chapstick, and pen. I also had water, bobby pins, post-it notes, a mini lint roller (lol), and thank you cards to write & deliver afterwards. You don't need much, but it helps to bring whatever makes you feel good.
