Healthcare Finance Summer Analyst at Raymond James

Monkeys-

I just received an invitation to interview for the Summer Analyst position within the Healthcare Finance group at Raymond James in NYC and had a couple questions. -The HR rep said I should expect to be there for 3-4 hours, is this typical for a first round in IB? Or is it more likely that they are just doing one round? -Has anyone interviewed or interned at Raymond James and can shed some light on the process and what type of questions I should expect?

Thanks in advance.
