I can't help you with any Atlas info, but I can give you some info on the lifestyle changes you are about to face should you succeed in getting a job offer there.
About 10 years ago,I was presented with the same opportunity that hopefully you will, in my case,though it was DC-8 freighters with ATI. The most shocking thing for us as a family were the scheduling issues. Up to that point, we were accostumed to the typical 4 on 3 off schedule that we had at my regional airline job,and it worked fairly well for us. But we decided to take the job offer for up to that point we thought some heavy jet experience would help move my career along.I don't think I'll ever forget my first call out while on reserve:
Skeds: "We need you up in TOL 0200 Hub time, Tuesday night"
Me: "OK ....do you know how long the trip is"
Skeds: "No"
Me: "Can I talk to someone who might know?"
Skeds: "Hold on"
Skeds: New voice comes on the line. "Yeah....Pack for 10 days!!"
An eye-opener, to be sure

!! I came walking back home though my kitchen door over 16 DAYS later. Quite different than what we we're accustom
to in our previous life and not good with 2 little ones at home, although my wife
God bless her never complained and was very supportive. The kicker was that
during that 16 day stretch there we're days that we didn't fly,specifically weekends when frieght didn't move. (remember this was all domestic flying. Overseas work might be different. I don't know.) Anyway think about how long you want to be away frome home Hope this helps
