CLK,is you are going to give charter a go I suggest the following:
Be prepared to work; Bring lots of commonsense; Be professional; Don't bore everyone with tails of "at Bla Bla Bla we used to...." ; Although I remember thinking I was a king when I got a couple of thousand hours, accept that it is only a drop in the bucket so most important of all, listen and be prepared to learn. Then it will be a breeze.
Good Luck.
