I did a lot of these interviews over the years and recently retired at the rank of Commander. You need to stand on your record. Hopefully, you began preparing for this day when your career started. You need to make the chief aware of your accomplishments in a concise, firm, but humble way. You need to emphasize your "people skills". You need to let him you how you will deal with your suborniates. Let him/her know that you will "take care" of them; you will provide those under you with training, mentoring, feedback and honest communication.
You need to stand on your record of a great work ethic, training and technical skills. Hopefully you excel in areas others don't. Don't badmouth your competition, just let him/her know you have knowledge, skills, traits they don't.........Best of luck......You in Redding? I'll be there in a few weeks on a m/c trip........Bob S>
