While I agreed with the article that most of the questions are pointless or at the very least suboptimal, I disagree that they imply that you're not getting hired. I think I've gotten some variant of "what are your weak points" in every interview I've been on (and I've been hired on several occasions. ;)). And I've sometimes asked the "I see you worked at company X doing Y... tell me about that" type of question as a sort of warmup before asking more technical questions.

Finally, I don't think the "how many gas stations are there" type of questions are totally pointless (though I don't generally ask them.) They reveal something about how a candidate attempts to solve problems, and the one thing you don't want to see is the candidate simply say "I have no idea..." without at least trying. I think there is a danger if a company over relies on such questions, however.
