Although the author is interviewing to be a tech writer, and this question may or may not be relevant to the job, it sounds like he knows a lot about computer science and even why this question would be asked at an interview.

I got the feeling the interviewee knew all this and decided to be a pain in the ass about answering it, anyway.
