They want the golden childs. They want 5-10 years experience but still balk at anyone aged over 40. You have to have an "upper level degree" but then again they don't want someone who spent too long in school. You need a breath of multi-disciplinary experience but also know absolutely everything needed to "hit the ground running" in their very narrow field. And of course they must be a good "culture fit". At anyone one moment there are perhaps ten such people on the planet.
I have met some of these people. They do exist. They are essentially walking professional resumes. They look great on the corporate website but rarely accomplish much practical work before they are off to live on a different website at an even higher salary.
