While there's definitely a lot of useless trivia (worse, useless trivia from 5+ years ago that no longer applies at all) in this list, the good parts of these questions _are the job_. If you don't know how to answer the relevant questions in this list, you aren't a good developer. There is currently an explosion of "front end developers" who don't know anything at all beyond "here's where I put in the bootstrap class to make the page look right" and "here's where I put in the angular expression" (or jquery plugin). Asking questions like this weeds them out.
