So what exactly are you preparing for? There is a 25 question multiple choice test pulled out of a bank of questions that you already hold a rating for. The HR is all "tell me a time" format, I am not sure you can prepare for those unless you are planning on making up something. The sim is a piece of machinery that you shouldnt have to prepare for, if you can fly a simple ILS with holding, then you probably shouldnt be interviewing. By the way I just gave you the entire gouge.
