I would suggest asking your own questions during the "Q&A" phase of your interview. The questions you are asked aren't particularly difficult and you won't glean much information about the position from them. Instead, I recommend you focus on how the compensation programs work in detail. Specifically, you should inquire about the "draw" option and the stipulations that come with it. Of course if you are bringing your own clients with you, don't worry about asking questions.
