I'm sorry, I don't think you've tried very hard at all to research this undertaking for yourself. The CP info at least is not difficult to find.
I second this Edward. A chief piot examination can be an open book affair where emphasis is placed in knowing where to look to find relevant information and legislation. Get this down pat by finding all the relevent information regarding the application youself. You are not so much asked to answer stuff off the top of your head in a CP interview, more, you need the ability show that you can competently find correct answers.
