A lot will depend on what your background has been. In some respects I found the training easier than some in the US and in other respects harder. No oral exam, and limited examining on systems. This also may just be a Boeing trend. No spoon feeding, but found the training to be very much like fomer military training, ie, be prepared for the session through self study and the debrief is where the training takes place. The "nit picking" debriefs is what I found most distressful. And some real lack of published standardization. Overall, IMHO, just be prepared for sim sessions.
Of course if you have never flown glass Boeings, or have Airbus experience to fall back on-Good Luck.
