Our players first visit was from the MLB area scout who administered the eye test and the psych test for MLB, told us how the process works, and also indicated that he was available for any questions at any time.
Actually our area scout usually holds a camp as there are so many kids who he has to contact, but son was unavailable.
Most scouts that have already gathered their information don't need to ask many questions, but rather want and encourage parents to ask questions, which we did. Most that I can remember from HS, gave an overview of the organization, where each level was located and living arrangements, which is a big question on a drafted player out of HS. Only one scout asked directly what it would take to give up college, but we knew many scouts and most knew he would probably head off to college.
A visit to the home gives them an idea of the families lifestyle, which can help determine signability later on.
Ironically, except for the top prospects, you might not even know who the scout is until you are drafted.
