My problem with the first point - Make them Design Something - is that design is a lot harder to grade than the second two. It's easy to see if someone can write fizzbuzz, or find the bug, but it's significantly harder to grade a design. Good design operates in the face of real world constraints, unlike typical interview questsions (see the article on Apple design about Real Artists Ship). As an interview question, I used to ask people to design the DB schema for Netflix. Almost everyone could get something that would kind-of sort-of work. Of course there was a gradient of bad to good answers, but a passing or better grade on the question did not help predict whether the candidate would get an offer. Asking FizzBuzz was a better predictor of whether they would pass the interview process.
