Ok, but looking at what I had done so far, it was very annoying to answer these type of questions. But I kept it cool :) It is funny how they miss on some of greatest talents based on a question about string manipulation. It is more like asking a professor to solve a fifth-grade question using what the fifth grader knows at school. Most the time they will fail. It didn't bother me not getting the job at all. It is just their loss. I have at least four other great opportunities with companies who appreciate my real-life significant accomplishments that I can choose from.
