I felt the need to study the overall CS content, so I listened to it. Since I majored in big data, I didn't have the opportunity to study CS in depth like computer science students, but I felt the need to study CS while preparing for a job. I also got a lot of help from Bigdol's book, <CS Major Knowledge Notes for Interviews>, and since there was a lecture, I listened to it to study CS. Good points 1) It was hard to find a lecture or book that covered the overall CS content, but I liked that he summarized only the important content in a short period of time. 2) It may be a matter of preference, but Bigdol's lecture style suited me well, so it was good to listen to. It could be boring if he was too serious, but he also made funny jokes and was bright overall, which was good. 3) I liked that he recorded interview tips in the special lecture in the middle and in the last part. It's not easy to hear the know-how of someone who actually got a job at a large company, but I looked back on my job-seeking process and found things I needed to fix. 4) If you leave a question in the community, he gives you quick feedback, and the content of the lesson plan is also informative. It's so informative and there's a lot of content, but for me who lacks CS knowledge, I'm grateful for anything. Disappointing points 1) The content of the lecture notes and the lecture ppt are often different. The lecture notes are usually a summarized version and the lecture ppt is explained in lines, so there are parts where you have to add content yourself. 2) As mentioned in other course reviews, there are parts where the lecture is not smooth. The lecture is edited a bit in the middle and sometimes it stops in the middle. If you find this annoying, it might really bother you. I enjoyed it I liked the lecture because I could feel the instructor's effort! It's the lecture I've listened to the most diligently among the lectures I've taken recently. I really want to do well in the interview and get a job, fighting! +) Do you like Big Stone, Mid Suits?! I was happy to see the two main characters in the background ㅋㅋㅋ
