Interviewing obstetricians???

Can someone do an interview of sorts with a doc before you choose who you want? I am a disabled veteran and the VA hospital has said I can pick whomever I want and they will cover it, however they pay a one time lump sum for the entire pregnancy so I don't believe I would be able to switch docs if I didn't like them afterwards. Have any of you met with different docs before choosing one? I am only 3wks. but I know the time goes by fast so I would like to get it all sorted out soon.
