First of all, there's no specific interview or application for such a thing... If they feel you are qualified, they may send you to the Dash Class... I'm not really sure of the criteria..
The 1st year Dash Captain Pay is 37.64/hr
There is a 18 month seat lock.
I am one of the "street captains" they hired in the first class which started in January. The class contained 15 People. Mostly made up of United furloughees. 2 guys in the class were former Mesa Dash Captains who moved on and were returning IE:UAL and National airlines... The few NON-UAL types had varied experience, mostly 121, Transport catagory A/C or Military, etc.
One guy, a CFI, will be an FO, but only until he has ATP minimums (Like 6 months or less)
So far, 2 Washed out completely. One busted the systems test, and one busted the oral. (Keep in mind this is a TYPE rating oral, like 4 hours) 2 others busted the Oral, but were able to re-take it and continue.
on 3/1 another Dash class begins. Supossedly another group of street captains. Technically everyone's hired as an FO, and you will submit a standing bid while in training. All but one in our class was awarded captain in the first standing bid... All DHC captain newhires have been based in DEN.
