Because there is a right and wrong answer. There is very little ambiguity, either the algorithm you wrote on the white board will do the the thing in required time/space complexity or it won't. Which makes it easy to ask and easy to compare candidates.
IMO this is horribly broken but the Big 4 do it so everyone else does too.
