Even for experienced professionals, preparing for CS interviews when switching jobs always seems difficult and overwhelming. Although I have practical experience, I struggled with how to organize my knowledge for an interview, but this lecture helped me find a clear direction. It was practically helpful because it didn't just list concepts; it taught me how to structure answers based on the interviewer's intentions and the flow of questions. In particular, I was impressed by how topics like JVM and GC were organized from the "perspective of explaining them in an interview." Previously, I had difficulty articulating what I knew, but after taking this course, I was able to learn how to organize my answers structurally. Also, since it is designed to prepare for follow-up questions, it felt like experiencing a real interview situation in advance. The core content is well-condensed relative to the length of the lecture, making it easy to listen to without feeling burdened. I highly recommend it to those who want to get a feel for CS interview preparation in a short amount of time. Even from an experienced person's perspective, I think this is a lecture that solves the dilemma of "how to effectively communicate what I know." I'm looking forward to your other lectures!! haha
