I heard from a couple of NetJets guys that on the whole, it seems to be a good company to work for. They seem to have a fixed number of days on then off (can't remember what it is). Lots of nightstops with a mix of destinations. They seem to pay a little less than some of the other corporate operators but the job security and expansion plans seem to outweigh any other factors. They will pay for you to fly from your chosen international airport so that you can get to work and then at the end they will fly you home. The Falcon 900 can be used on routes to the US and that carries a cabin crew member. On the smaller types you have to be prepared to tidy up once the passengers have left and make sure that any catering is on board etc etc since you have to combine the roll of hostie/pilot. It seems that guys on their first job or who are progressing up the career ladder usually fit in well but some of the ex-airline guys who joined in the current downturn, sometimes find the change a bit of a struggle, since they are so used to the cabin crew doing everything down the back.
I think that is all that I can remember. Hopefully it is a reasonable guide to what you could expect.
Good luck!
