But do you want someone who cannot handle an interview?
Perhaps take-home testing works if you want a "code monkey" who can sit in a box churning out code according to specifications, but I cannot think of a company that doesn't want more. The ability to interact with others in sometimes stressful environments is, imho, an essential skill for all.
There is also the danger that companies will turn these "tests" into work product. I did an interview last year (legal) that requested "writing samples" on very particular and timely subjects. Once I realized the game I asked them to sign a copyright agreement. They got screaming mad and tried to get me to sign all sorts of NDA junk.
It seems as part of the take home that you spend 45 minutes discussing your implementation and defending your choices in person with the interviewer. This is a much more realistic "on the job" stressor than being able to code out loud / on a white board.
