Sorry fail to see the actual point that you are making in your last post ??
If CAC are interviewing then it is reasonable to assume that they have identified a need for an instructor and are capable of "resourcing" that need.
Based on the posts so far it would appear that all is not as it might appear at CAC. One reason for multiple adverts might be unreasonable or unrealistic expectations (normally running alongside large personality / ego). Just a guess to stimulate some debate.
