I do mostly agree. However "luck favors the prepared" How your interview goes, sure there is luck of whats a good question for you. But being prepared increases your chance of a question you know. There is a finite number of questions you could likely get asked. Being more prepared for an interview and having practiced those skills, you might have a better chance at a 'bad day interviewer'. I do agree luck or chance is a huge portion of it. But I wouldn't quite say 99% as some would say, all of the time.
