There was one person on this site who looked down at candidates (for a normal software development job) who didn't answer his interview question well. And by well, I don't mean being curious and working it out on the fly, I mean that if the candidate didn't know the answer of the top off their head, the HN commenter deemed them uncurious and unsuitable. The question?
"How do mobile phone towers work?"
Interesting. In my experience, the US still has one of highest food qualities in the world, especially when you take into account it's diversity and variety. Sure, some things get missed here and there, but it's also a lot easier to be safe and consistent if you aren't producing the types of food the US is.
