Class dates depend on how many slots they have to fill. I know they are running one class in November, and one in December that is all they have talked about so far. I think all of the people getting hired now are being placed in a pool.
The gouge on aviation interviews was spot on, and they are still giving the 3 tests. Plan to be there till at least 2pm if you pass the tests and move on to the face to face part. The first test you will have the COG test, which you cant really study for. Then you will do the personality test. They will give you 240 questions, and you have 1 hour to complete. Then the job knowledge test had 60 questions, and they give you 60 minutes to complete it.
The face to face is pretty straight forward. They go though your log books before you go in, and that is the first thing they talk about. They will go though all of your school records to come up with questions about where you may have struggled in school. Other than that it was all TMAAT questions, and a few scenario questions.
Good Luck!
