Gone In 60 Seconds

If I had one minute to evaluate a job interviewee, I’d put a piece of writing in front of them (either code for a developer or prose for a less technical person) and watch them type it into an editor in real-time. If they are able to do so quickly and with few errors (for some values of quick and few), they pass.

This is completely unfair, and heavily biased towards certain privileges; many otherwise excellent candidates would be missed. But as a first-order approximation, I’d be willing to wager it works more often than not.
