its hard enough to identify problems and i think you don't need a well thought out solution before you can start to explain the problem. Maybe the next post will be "Do Hire by Ability to multiply numbers in your head", because that worked out well in practice. Or not. I liked the article and i think these kind of question are harder than they look. Demanding solutions is too much.

Once place actually did ask me to square a number in my head. Other than a brief flash of insight that you can do something like: 37^2 = (30 + 7)(30 + 7) = 900 + 210 + 210 + 49, I'm not sure what this was supposed to test. It was a fairly small company, but I'm sure they could afford a calculator or two....
