Each BGO is free to develop his/her own interview procedure. Personally, I prefer to have the parents present for the first segment so we can discuss the admissions process, field questions, show the video if the candidate or the parents haven't seen it already, etc. Then I request the parents provide the candidate and me a quiet place to do the interview in private. At first I did interviews with parents present, but it became obvious that some candidates were hedging their responses to my questions. They were reading their parents' body language and gestures. The content of the interview is controlled by USNA to a large extent. Best wishes to those of you with interviews coming up in the near future. Generally they aren't contentious so don't get too freaked.
