Consider the role of experience in a job listing. The job listing might want someone with 5 years experience and expert status (“rock star” or “ninja” or “guru”) in a several technologies.
This is, of course, impossible.
True expertise requires years of focused and deliberate study.
But the “required experience” in these job listing is a red herring.
Experience is a stand-in for value, the value being the capability of getting the problem solved.
“Experience” is supposed to indicate an ability to deliver solutions in a timely and cost effective manner, regardless of subject matter expertise. Some times it does, sometimes it doesn’t.
Experience, really, is a marketing strategy.
Experience is also a social construct, but that’s a discussion for another time.
