I wore my All-Weather Coat to the interview. It was the coat we were issued in Boot camp to wear with our Service uniform (dont laugh)😀 - I am quite certain that if it is cold/raining - a slightly more protective coat is appropriate. I know for a fact one guy did roll in with a black leather jacket. After you walk through the front door however, the coat goes over the left arm - and you are all professional.
