In a modern environment, never have I been asked to solve a business problem with:
No internet access, No configured editor, With massive time pressure, In a room full of strangers, In my chicken scratch with a fat marker.
It's not that whiteboard interviews are bad. They're just severely outdated.
They stem from a previous time before it was cheap and easy to interview engineers on actual hardware.
We know that whiteboards are a bad metric. Dozens of scientific studies show that the most effective hiring practice is a general intelligence test coupled with a work sample test.
It's easy enough to create a coding problem as a work sample.
Why do we test a proxy for the work, rather than the work itself?
