A lot of comments theorize about what characteristic - for the most part other than coding skill - these kinds of interviews select for. Mostly it's to justify their use. OK, then: is there any evidence that this style of interview effectively or efficiently selects for any particular characteristic that matters? If these companies were really as data driven as they all claim to be, they'd rigorously analyze predictors of success (whatever that means) within the system they've built, and then design an interview process that can rationally be expected to select for those characteristics. Having worked at one, interviewed at another, and heard lots of stories about the rest, I don't get the impression that any of them have actually done that.
