BS/MD Interview Case Western Reserve

I’m visiting Case Western Reserve University in August before applications and I’ll be doing a BS/MD interview. Can someone tell me what I can expect to go through? Should I bring a resume? Are the questions going to be similar to the real interview later?
To clarify, this is not the formal “interview” that applicants go through later on in the process if they are invited to do so. Apparently, it’s to “get to know the applicant.”

Any advice?

My son did an interview at Case in July and it was definitely the “get to know you” interview. He did take his resume so it gave him and the interviewer (a 4th year student) something to talk about. He said it was pretty casual and he didn’t feel like it was a stuffy job interview. They just had a 15 minute conversation about what he likes to do, what he’s looking for in a school, etc. Afterwards, the interviewer retrieved us from downstairs and sat with the whole family to answer questions in the private room. The setup of the interview seemed quite formal in the private room, but the overall conversation was casual.

I thought that the on-campus interviews were for undergrad only, BS/MD interviews are invitational
