I agree, although this is why I feel a small project and participation in code review is a more realistic and useful gauge for real world ability.

Can the person understand the code base well enough to propose a sensible change, and how collaborative are they in the code review process? Do they document/comment their code, add tests, do they answer questions and take criticisms patiently, is the solution simple, does it work?

You'll learn about zero of these things watching them write a fizzbuzz in a shared editor window.
