The thread reminds me of a story my brother told me years ago about when he was hiring for a games programmer position.
He remembered a good question from _his_ first job interview - "How would you find the intersection between an object traveling in a parabola and a plane?" The interview went from this question to: How would you find the intersection between a parabola and a line in two dimensions? How would you find the intersection between two lines? ... What's a cosine? Each question getting the answer "I don't know". It must have been horrible for the interviewee.. -- Jasper
