This is spot on for the interview I had. I went through several job interviews a year ago, which gave me a lot more confidence for this one. Generally, I would say be genuine, be friendly, and do your best not to make yourself overly anxious.
Also, if you're anything like me, after interviews I ALWAYS think of more things I should have brought up or clarified. These are great things to include in your follow-up thank you letter or email.
Good luck!
