Intuit interview questions

I have been asked to talk about my last year and anything about my other years. After a few minutes the Indian guy has hushes up to technical questions. It was putted a laptop in front of my with Google Chrome opened on Developer Tools. First of all, I was asked to say would be printed on console.log about a trick Javascript Hoisting test. It was a very trick question. In my opinion, it was a question which shows what exactly what they are looking for. For me, they have been looking for a master ninja of Javascript tricks developer, absolutely no sense. After that, I have been asked for write down a code in a piece of paper to identify in a give string all brackets have been closed in pairs like a HTML tag. Which should return true ou false also, should find bad brackets closed and return false for instante, "AB ] CD [ EF ] GH [ IJ". By the end, I have been asked to describe how to find out a specific ball between eight balls. The question was: You have eight balls all of the same size. 7 of them weigh the same, and one of them weighs slightly more. How can you find the ball that is heavier by using a balance. I should also describe possible outcomes.
