As a complement to the project-based interviews that John mentions, we recently did this at Khan Academy with a candidate and are doing it with another this week. It's difficult because not everyone is free (or is interested) to take a week off what they're currently doing, but we're excited to keep trying this as it's a very valuable signal.
