OK, we get your point. But consider that there are jobs where this stuff is actually important, and it's useful to have working knowledge. If you were actually going to ask this in an interview, you would obviously want to ask something different but along the same lines, just in case the candidate was familiar with this post. But that goes for many interview questions.
For the jobs where this is actually important, this isn't a good interview question - it's not subtle/deep enough. (There are many deeper questions for those jobs - this one is a basic intro level question for a job such as that one.) The reason I enumerated so many ways this is wrong isn't to be funnier: it's because I really want people to stop doing this.
