If I understand correctly what you are saying I fully agree with you. If one ansp has found you not suitable in the end to be a controller, you probably will end up not suitable for any other ansp as well.
The thing is that I can honnestly say that I am capable of becomming a good controller, but a very harsh situation in my personal life has sadly intervened with my training. The mistake I have made in this was not being completely open about this, a mistake I can definatly say I will never make again.
Anyway, as I said, I understand your opinion 100%, I can only hope I will find one ansp who can understand and trust my opinion as well and give me a second chance.
Thx again,
