You have an O9 interview/appraisal and you’re worried? Unless that admiral didn’t give you all 10’s and a crappy write up, then I’d be a little concerned, but sounds like you have a solid chance at selection. I have x3 CAPT and x1 CDR interview/appraisal with really good write ups, perfect 10’s and feel pretty good about my chances this board. Evals, ASTB scores, and ranking are all good indicators of your overall potential. So unless something is off, I wouldn’t worry about it too much. Just my perspective ??♂️
