The first class was 9 and is just about done, the next class I know about through aviation interviews is I think jan 18th or around the mid jan timeframe. They are not really hiring internal FOs, they offered it at one point but there were no takers and I know for a fact of a few who wanted it and could not get it so who knows. I would imagine if they cant fill the right seat they will try again for internal. I would imagine not many takers though because why move to the Q when upgrade is less than a year away in the saab.

They need I believe 75 FOs and they have 9 so far

EDIT- I just saw this link http://www.colganair.com/jobQ400.htm It is in regards to upcoming interviews and by the looks of it they are not looking for 340 FOS they are aggresively seeking Q FOs and and 340 CAs
