I'm a computer science major, but while preparing for job applications, I had difficulties with coding tests and spent a lot of time studying on my own. I bought various courses and studied, took several coding tests at large companies, but when I saw problems in actual situations, I was in a difficult position where even deciding which algorithm to use to solve the problem was challenging. So while thinking about how to study more, I discovered this course. First, there are live lectures every Monday where the instructor provides brief explanations and Q&A sessions about the concepts to be covered during the week, and you can also watch concept videos on Inflearn, which was a great help in catching up on concepts I missed. The quality of the concept materials provided is excellent, and since the instructor creates high-quality animation materials for problems that look difficult when you just see them, it was easy to understand! Also, when preparing for coding tests alone, I would wonder "Should I solve this problem too? I probably don't need to solve this one, right?" and worry about which problems to solve, but I think it's a big advantage that the instructor selects problems that are very important for understanding concepts and provides them as assignments or study problems. Additionally, the instructor provides immediate code feedback and answers questions right away, so when there were parts I was stuck on, I could resolve them immediately, which was great. Since the difficulty level of the problems isn't easy, I recommend that complete beginners take the all-in-one course first, but if you're a computer science major, I strongly recommend participating in the Killing Camp right away! (I passed a coding test at a large company while participating in the Killing Camp and am currently preparing for interviews!!)
