I think the whiteboard experience is very loosely correlated to programming ability and hope that the simple loop fiasco was an exaggeration. Many good programmers have a great deal of social anxiety, and being put under the microscope is not how they work. A better test of their prowess would be to hire them as a contractor if they can talk shop and have some live projects/open source code out there that isn't obviously copied. Short of that you could always stick them in a room for half a day, with an internet connection for their own laptop, ask them to solve a problem, then have them explain their rationale, stepping you through the code when they are done. Either of these would be a much better measure of how the candidate would perform for you if hired.

It's not an exaggeration. They can't do FizzBuzz. I would expect at least that without the use of Google.
