I don't know what all you need to know, but this is what I know....
They have 4 bases - MEM, HRO, PIT, DAL. The majority of the operation is based in MEM. They have a Global Express, 3 Challengers (601), and 7 Learjet 45's. The Global, Challengers, and 3 Lears are based in MEM - the outstations have Lears.
Quality of life is excellent...you are salaried to work 16 days per month. Most of those days you will be flying or on standby to fly. But, you also may be in training, traveling (ie-to training), or office duty. Other than those 16 days, you are off...not on telephone alert any of that stuff. If they need a pilot to fill a trip, they may ask you to fly an extra day or two, but they will pay you extra for it. You do not have to accept a trip on your day off.
Pay is not all that great.....It is a little less than industry average, but schedule kind of makes up for that. If you want to make more $$, go fly freight at FedEx. That said, if you want to fly freight, you can cross over from Corporate to the "line" after 3 years if you meet their minimums and they are hiring.
If you get an interview at Corporate, the interview process is the same as the "line." You have to take a sim check, do testing, and the panel interview. The panel interview will include HR, a line Capt, and the Corporate Aviation Chief Pilot. It's a pain in the arse, but worth it if you get the job offer.
