I have a very reserved personality, so I listened to the preview and the instructor's tone of voice was quite high-toned, so I had a lot of concerns before paying. However, the instructor really made the lecture fun enough to make me laugh a lot, and the content was really good, so it was very helpful for reviewing overall knowledge. I'm not aiming for a large company, so I don't think I'll get asked these questions a lot during interviews, but I think it'll be helpful for me if I learn it because knowledge is power~ By the way, is the person with the nickname "Keundol" who wrote the review really you? I'm so curious that I don't think I'll be able to sleep ㅋㅋㅋㅋㅜ
