I know a few guys who went through the scheme, all be it a while ago now, yes they were worked hard and did lots of crap jobs,but the training they received was second to non and they went on to or are going to go onto great careers in the industry.
My advice to anyone looking at the scheme is grab it with all appendages !
Also, if you are going to do some of your training with Propilot ,then again grab the chance ,it will be one of the most interesting and enjoyable times of your career.
