  1. Great questions to make sure you're hiring programmers who know their fundamentals! Might want to throw in a few difficult questions though too, just to mix it up a bit. In my opinion, these questions are common knowledge. Instead of having a question ask for a definition type response, what if you gave a scenario that describes a piece of code, and ask what is being used that allows the code to work properly, or something similar? Perhaps even put in a few incorrect lines and see if they're picked up on. This would show experience with using these principles, instead of just the memorization of them, which won't help much in practice. Other than that, these are great!
