All I know is that there's 50 FO positions available. As for the number and quality of applicants I don't know. Kura's handling the recruitment. My response you quoted was for Sarah as she was asking about Flight Attendant/ISR positions.
The advice of being careful what you write, think about who you're applying to and what you can bring to the table so to speak. If you're in private aviation, you'll know that our job is a lot more than just flying.
The above links should help.
I must warn, if you are looking for a fast upgrade, NetJets is not the place.
