Sorry bud. Company sim supposed to be easier, much easier than the CAAC check ride. So your challenge will be convincing the agency you are worth progressing. The Chinese and even HKers seldom tell the truth to your face and if they say they don't know that's just their way of saying we cant be bothered to risk it. In theory possible but the agency must be willing. Fail the CAAC check and then it's a mandatory 1 year wait but again the agency holds the key to get you into the recruitment process.
