Private placement?

Can someone shed some light on private placement agents or “finders”? I got an interview for an entry level position from a small advisory firm that specializes in private placments. I haven’t had luck with BB or other full service firms so I guess beggers can’t be choosers. But I know so little about this particular niche. Can someone tell me what entry level analysts do exactly in these firms and what the exit options are? Can you move to traditional IB or ER? And comps compared to traditional banks if possible? Thanks!!
