J.O. writes, "When a writer gets close to having an agent offer representation, what sort of questions should they have prepared to help them determine if the offering agent is 'the one' when they get the 'the call'? (Like many of us would actually say 'no' to someone we had queried and who thought our work was saleable!) Are there no-no questions? Are there some essential questions? Are there questions you wish writers would ask you?"
