It feels too much like a non-expert giving lectures. Rather than acquiring professional knowledge, the teaching is too superficial. The content is weaker than the IT infrastructure lectures from Naver Cloud on YouTube. I thought learning together with students would compensate for the instructor's insufficient explanations, but it feels like taking a class with a friend who doesn't know IT. Since they're non-IT people, there are no sharp questions and it just feels like only talking about costs. The most frustrating part is questioning why "developer" is in the course title. For aspiring developers, the essential knowledge they should know and useful knowledge to have are learned very superficially, so it seems more like "a course for non-majors to quickly understand IT." To summarize: The course depth is too shallow and unprofessional. -> A few Naver Cloud YouTube videos and Red Hat technical documents are more professional, or it would be better to search for information on each lecture topic individually. The unique class structure only extends lecture time -> Although they said non-major students, it would have been better to bring IT industry job seekers rather than people with personal connections.
