I am so impressed that you share your knowledge for free.. However, as a non-major, it is very difficult for me to follow the content. It is almost like a knowledge assault. New concepts and content pour out like a waterfall, but since you have so much experience, it feels like you are explaining it to yourself, as if you are saying that the professor must know this much. Rather than the concept of a lecture, it feels like I know this much in front of the interviewer. I think some prior knowledge is necessary, so it would be better if you listed it in the lecture introduction.
