This is what the FAQ has to say
You should only ask practical, answerable questions based on actual problems that you face. Chatty, open-ended questions diminish the usefulness of our site and push other questions off the front page
So, from this, if we look at
they both appear, if you do a quick google search, in lists of standard interview questions. These are most likely not from practical experience, actual problems being faced, etc.
Add to that this question here which also looks a lot like an interview or school exam question and I think we're starting to see a pattern where some people are using this site, not for practical and useful research but, instead, to short-cut interview processes and school projects.
Currently, the FAQ does not specifically call out "don't ask interview questions". Should it be updated to do so?
