Yes, I agree some very good points made by newbie and Jockey.
The reality of Command training is that you may be paired up with someone that doesn't quite understand where you are coming from and what special needs you may require. This can cause a chain of events that can create perceptions that may be difficult to turn around in the remaining Command Training time available.
A talented trainer will be able to extract the very best from any raw material that he is given. A gifted trainer will even be able to take a previously crushed trainee and rebuild him to the extent that he regains confidence in himself so that the end result then becomes a given.
A highly talented and gifted trainee will excel with virtually any trainer the system throws at him, but of course these trainees are more in the minority.
The system is designed to give the trainee the benefit of the doubt. So don't waste the opportunity.
It's your Command course. Don't let anyone take it off you.
Somehow the corporate knowledge seems to know when someone who has unfairly missed-out, has been hard done by. This message is not lost and invariably such a candidate seems to sail through on the next go. These Commanders then seem to go on and eventually make the best trainers.
We even once had an FO who was Cat D’d due to his affiliation with the AOA. The hue and cry from the senior pilots (and one gentleman in particular taking on the management) soon had this situation reversed.
CX desperately needs Commanders. The CX Command training is expensive. So they are more interested in successful outcomes then you are (if that is even remotely possible!).
