Casual in tone but straight forward. Not many personal questions. More business and future goals- asked about previous employment and experience, where I see myself in 3-5 years, what I hope to learn and what educational backgrounds I have. You should dress to impress, I have heard many people go in with casual dress clothes. Wear a tie. No low cut tops, no excessive jewellery, hair done, I would recommend a breath freshener as they are relatively close to you, just make sure you throw out any gum or candy, have a cover letter prepared and additional resume specifying skills and knowledge related to job. Try not to use the same general resume you applied with so it shows your keen interests
