I am a first year and absolutely love my school. My 1st year was acutally a really happy, fun year for me (of course there were stressful time, but everyone has those). I would say just be yourself and show that you have a personality and interests outside of studying. I think that is highly valued at Drexel and it's what I look for when I do student interviews.
I just realized that you had your interview already. Hope it went well.
