You will be watched and standards upheld. You will be asked a lot of questions.
Another thing, when you are assigned someone who you will work under, I won't be one of them as I am busier than a one legged man in a butt kicking contest! Diplomacy, medicine, day to day operations, yeah, you get my drift!
So, read the questions. You don't know which ones you will get and STUDY!! If you still want to be one of us, RP with a few of us, get a recommendation and apply.
