Have a friend that worked there. They are a well run company and treat employees well it seems, but you will not get much flight time. My friend barely cracked 250 hours in one year of flying for them.
The real issue is, they fly dual crew on all of their missions. Good for safety of course, but there is no way for the non-flying pilot to actually log the time. So half of the time you are spending up in the air will be useless from a flight time perspective.
