Max McKeown has a very interesting post on Management-Issues about hiring people for how they learn and not just for what they know. He discusses how hiring someone because of what they can do now is too limiting when things are constantly changing. You need to hire people who can adapt to the future and innovate (there's that pesky I word again) - and these are capabilities we need to learn and constantly re-learn/update. I have had many a conversation with managers frustrated with employees for whom their job outgrows them (and many senior leaders with the same complaint about some managers). Check out Max's post here.
And if you are a candidate, make sure you tell the employer about your learning style and recent learning successes.
