I had an interview at O'Reilly several years ago and was given a piece of paper with some Perl code on it and was asked to comment on the code. The only problem was that the font was so small that it was literally at the border of what could be seen. I felt it was more a test of my eyesight than my knowledge of Perl. Brain teasers are a two way street, they can say a much about the person giving the test as the person taking the test.
