Hello,
Good company to work for, and as far as QOL of life. It depends on your individual situation. If you are single, I think it would be pretty good given the runs that they had when I was there. The junior runs have some longer duty days, but weekends and holidays off. The good news, is that you won't be junior for too long and an opportunity exists for rapid advancement to the twins. I was very fortunate to fly the Seneca, Cherokee 6 (my favorite) and the Lance. The Cherokee 6, while not a twin is the BEST airplane to make money with and operate on the kinds of runs "Race City" does for a living. However, multi time is where it's at for advancing your career.
Equipment is pretty decent, and most of the airplanes had an IFR GPS installed and the plan was to standardize on the GNS-430 in all airframes. Sure, you'll have a few MX issues now and again, but maintenance was good in my opinion. Be ready for less than perfect, but safe airplanes.
The flying is great and I find myself missing it from time to time. Make the most out of the experience and be humble. Enjoy the days of flying a light-twin single pilot IFR... and be humble
