Meeting/Office Visit with AM/HF? HELP

For background I currently work (temporary gig for placement year at uni) at a PB/AM for their HF research (FoF) arm.

Recently at a conference I met the head of Business Dev (and son of the late founder) for a ~2bn AM/HF firm (they have some long-only and one l/s I think). I spoke to him for all of 2 minutes and expressed that I was looking for a summer internship before he offered me his card. It probably helped that my current firm has holdings in one of the funds (but he knows I have 0 say over that).

I'm in the process of scheduling an office visit with him to "meet a few people". Not sure how long this will be and what it will entail. He knows I'm after a job and has asked for my CV but this seems more casual than an interview. What do you think I can expect? What should I know? What should I ask? Really, I'm after an equity research position if I can get one to build my skillset and experience in time for grad recruiting.

Thanks,
