The reason CTC can claim 100% (if they do...) is because pilots who qualify but do not gain immediate employment will sit in CTC's own holding pool until they do get a job.
Some guys might be in there 6 months or longer, essentially unemployed, but providing they do get employed eventually, ctc could say they have a 100% employment rate.
In this case I think all FTOs could claim 100% employment rates, I just think CTC's marketing is quite sneaky.
As the old cliche goes: you can make statistics say anything
