They're fine but they need to be understood properly. Whiteboard interviews don't really capture how well someone codes. They are better at capturing thought process, high level understanding, system architecting ability, and a candidate's communication skills. If you want to see how well someone codes, look at their code. Or ask them to write something for you. Don't do a whiteboard interview and think it is the end all be all. Take it as a data point.
