There is no standard...in fact, I suspect there is a lot of variation in how , when and where BGO d0es their interviews. I live in a rural midwestern state, and know that some of the BGO's travel to the Candidate's home, sometimes > 1 hour away,, others meet at a library or diner in between, and others have the candidate come to them. I usually do my interviews at my office, often on Saturday AM but work around the candidate's schedule. Interview usually lasts 1-1.5 hours, including one of the USNA videos. I don't typically meet with parents, but give the candidate my card and ask them to have parents call me directly if they have any questions. An hour or so is enough to get a pretty good sense of the candidate--bey0nd that its usually answering questions and telling sea stories. As anyone who has done interviews before (job interviews or BGO) can attest, the time either flies or drags. I try to do an initial write up the same day, sit on it overnight, reevaluate then post it within a day or two.
