Definitely talk to your sub class advisor as well for interview advice. Idk if the Admiral will know your service selection rankings but I imagine he/she doesn’t want you to blow smoke up their ass when they ask “where did you rank subs” and you say “oh right at the top!” There’s got to be a tactful yet professional way to answer along the lines of “to be honest I didn’t even rank subs on my sheet, but I understand ROTC is an officer first assignment second contract and I accept that, and I would put forth the effort to gain the respect your community is looking for.”
