[PubQ] Agent Call before Full

I uploaded my full manuscript last night at the agent’s request, after they had read the first 100 pages of my MS. They just emailed me this morning saying that they loved the book so much already they would like to go ahead and schedule a call this week.

I’ve never had a call with an agent, and I have no idea what to expect. Is there anything in particular I should have prepared for it? Is it too soon to hope that the agent might make an offer of representation?
