Training is unpaid. You must not be scared away by hard muscle work. You (normally) receive a loaded aircraft in ANC, but unloading is done by the crew or at least with the help of the crew (unpaid). If you are required to load the aircraft in an outstation (or in ANC for some reason) you will receive extra pay for that (lots of salmon boxes).

There is definitely good sides to it, you are home in ANC every night and if your schedule has you leave in the middle of the night, you are off work early in the afternoon. Yes, the 14 hour max. duty time is observed.

Don't know if and what minimum numbers they have. Keep updating your resume often to make sure you are on the stack when they are interviewing for a class, which is not too often a year. They seem to be a decent company to work for. It's multi-engine, turbo-prop, multi-crew, lots of real IFR flying, what more can you ask for? Surprised they don't make you pay to fly there, right?
