I agree that the technical screening can go away and be replaced by a chat. I've gotten to know new employees at my work by going for a beer with them and asking "Oh so your iPhone's jailbroken? How'd you do that?" or "So I saw you're using Gnome3, why do you prefer that?" and most of the time they're pretty eager to give a well-thought-out explanation behind those sort of personal computing choices. I really enjoy working with the people who are well-versed in some niche topic like that and can communicate its 'good-enough practices' well.
