Yeah, a lot of this stuff seems sort of obvious, but if it's so obvious that these questions are bullshit, why do interviewers keep asking them?
Thankfully, any smart interviewer already knows this. Being asked these questions is a sign you might not want to work for these people because they are not very smart and/or don't think about the things that they say.
To be honest, in the interviews where I thought "wow, these people know what they're doing", they did not ask these questions.
Quite often, the most random and insight-free blog posts containing no substance or logical deduction are upvoted because of a strong title. For some reason, some readers try to pull out whatever tiny bit of insight that the article might contain, to make up the for the time lost reading it. I say, write it off as a loss and move on. There are no logical deductions to see in the article.
What does it matter if a certain question shows up in an interview? Why try to analyze every word? In the end, you either did well, or you didn't, and they either did well, or made a bad impression on you. Just answer the question and remain friendly whether you still think you're interested in them or not--not all questions are going to be highly technical. At the end of the day, it's just another person sitting across the table.
