When I hired a plumber for my heating firm, I put her through a hazing interview, tested her knowledge of Maxwell relations and thermodynamic equations.

Why? Not sure. Everyone else does. I mean, hiring in IT is shit, why should we break from the industry norm? Why should we want to care about the candidates? Right? I mean if Google can do it...
