Just a warning for those tempted:
Whilst these jobs may seem ideal, do be warned that you're in for a life of very high working hours, being grossly mismanaged, in a company where you are treated with disdain by most other departments, and even if it survives you won't get a command for decades.
Those who take the jobs may reflect on this warning in a few years time.
Sorry to be a killjoy, but I wish someone had given me this warning several years ago.
