Liz Ryan makes the case for T-shaped candidates, without saying T-shaped:
When we exalt and reward career ruts instead of career exploration by hiring cookie-cutter candidates who meet our delusional job specs but lack any spark or vision about their own paths, we sentence them to more of the same thing they’ve already done. We sentence ourselves to less and less creative thinking every time we hire someone to reinforce our status quo.
If you have two smart candidates and you can’t decide which one to hire, hire the quirkier person. Hire the person who has a story to tell — a human story about choices and interests and passion, not a story about pleasing authority figures to keep moving up the corporate ladder like a dutiful Career Person, with no higher end in sight.
