VJW, I am not in the same boat as the OP even though my posts might have indicated that. I have actually applied but that is just a week ago, it's still too early for me to have concerns! I am just curious to know if there is any logic behind their invitation process as I do not want to randomly have to wait for a year before being called if I meet their criteria.
I did pass first attempt on everything throughout my training though, so if that happens to be one of the things they go by I guess it's a good thing for me.
