Given that the BGO interview is supposed to be done before your application is complete, I would say no..
Of course, like anything, there are probably exceptions.
DS finished his application, BGO interview by the end of September last year.
Cleared DoDMERB in October.
Received LOA first week of November, one week later, had MOC interview. They knew his LOA.
Remember LOA is not your goal, an appointment is.
