The last 5 or 6 new pilots I flew with had between 3000 and 7000 hours when they joined, the majority had command in their previous company, and around half had a lot of jet time. Most are ex-airline or ex-military, or both.
I enjoy it, but it is not for everyone. You can have quite long days, and you have to think on your feet and do quite a bit of problem solving. You work for 6 days, and that 6 days could take you literally anywhere, so if you are a fan of routine it is probably not for you.
The roster is very stable, you know the days you are working, I do not get hassled by the office on my days off. The aircraft are very nice and you work with a great bunch of people, I happen to think that the fleet I am on is the best, funnily enough the vast majority of my colleagues on other fleets feel the same about their fleet
Yes on busy days it can be a little crazy, and I have had my share of getting fraught with the office and them getting fraught with me when it starts going a little "pear shaped". At the end of some tours I have been absolutely exhausted. Other tours have been pretty low stress. I have been to some amazing places (some places I won't miss if I never go there again!), and as I said earlier 99% of the colleagues I have worked with are a pleasure to spend 6 days with (I just hope they think that about me!).
The contract and salary/benefits are something that depending on where you live or are taxed can be a big issue, look carefully. There have been many changes in the last 18 months, and while there are still things that could be improved, on balance, I think overall it is pretty good.
I am sure that other people will have other views, and there are plenty of opinions on pprune about netjets, from past and current employees, read, digest, make up your own mind. I offer one last thought, the perfect company for everybody probably doesn't exist, so in the end you have to go with what most matches what you want out of life. Have a good day.
