I never thought I would write a review again. The previous score was 5 points. It was a review I wrote when I finished the first week, but I am writing it again after I continued. The most difficult thing about coding tests is that since we are human, we basically write under the assumption that it will work as we intended, so it is not easy for us to find logical errors ourselves. Of course, it may be easier for others to find logical errors than for ourselves, but it is harder to understand the overall intention of code written based on the assumption of others' intentions. That is why most academies do not try to look at students' codes. Instead, if there is a part that does not work, they create a new one and teach it. However, Mr. Bigdol is different. Of course, there are things that need to be looked at due to the nature of the coding test, but in my case, I try to limit my questions as much as possible and ask the GPT about logical errors first, but sometimes even the GPT cannot find them. Mr. Bigdol personally analyzes the code syntax one by one with a craftsman's spirit to find counterexamples. Current developers or those who have taken coding tests will know. Finding counterexamples (debugging) is more difficult than writing code. There is one more reason why I recommend it. Most other lectures are like this problem, you should use brute force~ you should use DFS~ but this problem should be approached in this way, so you can solve it with BFS, but it is more efficient to use DFS. This is how the class is conducted. I hate classes like this, like entrance exam classes, where they say, "This is a formula!", but I think the quality of the lecture is quite high because it helps you understand the principle itself. I hate spending money without meaning, so if you can prepare on your own, I don't think you need to take this lecture or any other coding class. Originally, coding tests are different from algorithm competitions in that you just need to meet a certain level of requirements. However, if you must take this lecture, I definitely recommend it. I personally thought the price was reasonable when I only looked at the lecture content, but when I comprehensively considered the debugging, counterexample finding, consultation, code review, class lectures, and material updates, I think the price could be raised a little more. This lecture is the cheapest right now, before your youth and passion cool down, this is the lecture that will bring you in front of the interviewer. ================== It's the best. Even though I'm a current developer, I'm addicted to the simple and clear explanations and the humorous wit here and there. I'm worried that at some point, I'll just build up an internal intimacy without realizing it. It seems like putting the lecture materials on a separate tablet and looking at them consistently will be good preparation for the interview. I hope you all succeed!
