The part where the guy chuckles and says that some of us could recognize this problem as part of their employment application at Google was a bit disturbing. It sounded innocent, but, ominous really. Just assume for a second that I'm not a complete idiot. Assume that I've been around for awhile, that I know how to perform summations, that I can do running averages. Assume that I've seen complications that come with solving some of these basic problems. Assume that I've solved problems before only to be confronted by subsequent problems in the pipeline, and assume that I've come to expect that kind of development. What in the world could my first impression mean to anyone?
