At any rate, the point is that a guy who used software used by a large portion of Google's engineering team because it was superior to the in-house solution could not get a job at Google because he failed to answer a programming question in the specific manner the interviewer wanted for a type of problem he would never actually encounter on the job. And in that vein, Sergie and Larry would similarly have difficulty getting hired at Google because other than their original algorithm, which Google has not used in over a decade, they have no modern or recent software experience and would likely fail all of the programming interviews.
