Contacting an OSO

Just sent in my info on the official Marine Corps website. Got the information for Officer at my local OSO. Gave him a call and set up an appointment o come in and talk. They are super friendly (more than likely part of their training) I was respectful, I mean everybody in the South use to be raised to yes or no sir so it was easy. Do not dress like a slob but be comfortable they are a resource for you to talk to. They are feeling you out when you go in to talk to them. First they want to make sure that you are not wasting their time. Second they need to get to know you because they ultimately will be vouching for you and your application. I was asked some standard questions like why I wanted to become a Marine Corps Officer. Also, asked about some tags with different reasons why you wanted join. You pick a couple out and talk about them. I knew it was kinda feeling me out but you have to be honest with them and yourself as to why you want to do it.
