Yes, but mostly no. I showed it to a few friends and a few of them had zero interest. Some tried for 30 seconds, then asked for the answer. Another wanted a hint. One said "I don't get it". One gave the answer right away and it was wrong. And some didn't get it after a decent step-by-step explanation, or even weren't interested in the explanation. That says a lot, I think, about a certain mentality of a person towards particular types of problems, challenges and learning opportunities. But I say mostly no, because there are hundreds of questions like these. Once you do 2-3 (and if you're in certain circles, you most likely have), the 4th or 5th become very easy, if they are even different (and not just a copy/paste) of ones you've already done. In short, I think the question can be meaningful sometimes, give false positives a LOT of times, and probably give some false negatives, too. (e.g. nervous people who can't think outside the box in an interview boilerroom which is an a-typical work environment in my experience). So yeah, I wouldn't personally ever use this in an interview.
