I'm a backend developer without a CS degree who joined a mid-sized company after catching the last bootcamp opportunity. Three years ago, I was lucky enough to get hired at a company that didn't require coding tests, but now I'm preparing to switch jobs to advance my developer career, so I took the Killing Camp 9th cohort course. This lecture became the motivation that made me prepare for coding tests diligently again. When preparing for coding tests, I was lost about what I was lacking and how I should even prepare, and when I couldn't establish a clear direction, I met the instructor and took this course. I learned how to prepare diligently, and if you immerse yourself in the 2-month program, a miracle happens where you can solve coding tests for your target companies within 2 months. (Places I couldn't even attempt before, by my standards) During the 3rd week of Killing Camp, I took a company coding test, and I remember that as soon as I saw the problems, I could immediately think of what type of approach to use to solve them. I was truly grateful to the instructor in my heart at that moment. The quality of the materials is great, and the methods taught are so easy to grasp that even those who are unprepared like I was will grow significantly if they take this course! Thank you once again, instructor, for giving me hope and aspiration to challenge my desired companies after passing through the period of frustration due to coding tests!!

I'm a Java backend developer who will just be completing my first year this coming January. Although I majored in computer science, coding tests were always a burden during my job preparation process, and I felt lost for quite a long time. Actually, even before starting Killing Camp, I was already receiving a lot of help by taking Mr. Noh's coding test video lectures and interview lectures first. Rather than just solving a lot of problems indiscriminately, he calmly explained what criteria to use when looking at problems and why certain approaches emerge, which allowed me to organize the parts I had been missing one by one. This naturally led me to apply for Killing Camp 9th cohort. What I liked most about taking Killing Camp was that it wasn't simply a lecture that teaches problem solutions, but rather it trained the actual thought process when first encountering a problem. By trying incorrect initial approaches together and pointing out why they were wrong, and what criteria to use when rethinking the next step, I felt my problem-solving skills building up steadily. Also, thanks to the explanations using animated materials, parts that were difficult to understand through text or code alone became visually easy to grasp, and were much more memorable when reviewing. And what was really helpful in Killing Camp was the feedback from Coach Sangju. Parts I had skipped over when studying alone because I wasn't confident, questions that weren't clear even with AI, the coach explained directly with code reviews, allowing me to understand properly. Now I'm reviewing the problems I solved in the camp, and even when I hit a wall in my approach like before, I can now doubt my own thinking and adjust my direction on my own, which shows a definite change. If seeing a problem itself was burdensome before taking the camp, now I can at least stand before a problem with the mindset of "Let's try to solve it calmly anyway." For those who keep hesitating because of coding tests, especially those who majored in CS but found it difficult to find direction on their own, I believe you can gain a lot through Killing Camp. Thank you sincerely for creating such great lectures and camp!

Even as a computer science major, I had never properly experienced coding tests before, but over 8 weeks I was able to transform a vague barrier into real confidence. While preparing for a job change, I wanted to seriously prepare for coding tests, so I first took the Coding Test All-in-One course, and then participated in the Killing Camp to focus on problem-solving. Going to a study cafe after work was never easy, but looking back, I feel really proud that I grew so much over those two months. The curriculum was structured so that problems gradually became more complex from easy to difficult difficulty according to weekly themes, which was great for building skills step by step. In particular, the daily evening co-working sessions and the goal-sharing system through Slack were very helpful for schedule and goal management, allowing me to achieve goals steadily without giving up. Seeing people working hard motivated me to stay disciplined and tackle problems day by day without becoming lazy. If you can utilize daytime hours as well, I think you'll gain much more by reviewing previous week's problems as you progress. In the beginning, even relatively easy problems felt difficult and I sometimes spent hours pondering a single assignment, but through repeated training of systematically approaching problems in the order of problem analysis - approach method - solution - lessons learned, my problem-solving speed improved to a degree that surprised even myself. The biggest gain was that later on, I began organizing problems by creating logical reasoning for why I should solve them in a certain way. After solving problems, I compared my code with the solution code while watching the provided solution lectures and solution guides to find improvement points, and thanks to the visual explanations of code flow, it was easy to understand even high-difficulty problems. Now I have confidence that no matter what problem I encounter, it won't deviate much from the problems I've solved. Thanks to the well-structured curriculum and the environment of working together with others, I was able to grow faster than I expected. It's truly amazing when I think about the confusion and frustration I felt in the first week. If even I, who thought I barely managed to solve the given problems each week, grew this much, I think those who can invest more time and effort will be able to grow tremendously. I highly recommend this to those who have similar concerns as mine, and to those who are willing to take on the challenge with determination!!

As a non-CS major, I've never systematically studied algorithms, so I always felt scared and wanted to avoid coding tests. I bought and took several coding test courses, but most of them felt like watching someone who's already good at it solve problems effortlessly, which often left me confused as a learner. Then last year, I took the Coding Test All-in-One course on Inflearn, and it really helped me build a foundation with visual explanations starting from algorithm basics and showing how to approach problems. That's why I signed up for Killing Camp. Killing Camp has quite challenging problems and requires solving many problems each week, so I think it's worth the money for those who have basic concepts down and can dedicate enough time! This time, I participated for 2 months with the goal of solving all the assigned problems each week, spending at least 2-3 hours daily, sometimes 5-6 hours. Each week focuses on a specific algorithm topic, so I could learn patterns by reviewing concepts and then solving related problems consecutively. It's not easy to consistently study for coding tests alone, but in Killing Camp, having others studying together during the set period really motivated me as we shared our progress, and I was able to participate until the end. I recommend this to those who are always held back by coding tests, feel lost about how to approach problems, and want to properly invest time to thoroughly prepare for coding tests!

Since my undergraduate days, I've always struggled with data structures and algorithms classes. Even after graduation, I kept failing interviews because I didn't properly prepare for coding tests. I tried various courses and books, and mindlessly solved problems. After much deliberation, I applied for and completed the 9th cohort of Killing Camp. Although the process of solving, analyzing, and learning from problems each time was difficult and overwhelming, I regretted not taking Killing Camp sooner. I believe that with well-prepared materials and systems, what you gain depends on how much effort you put in yourself. The abundant and diverse materials helped me understand well, and it's reassuring that questions are answered with quick feedback. Through Gaebalnamnoh's live lectures every Monday, I could communicate and being with other passionate students in real-time was very motivating. The daily evening study sessions were also a great help. Please make sure to participate in the daily study sessions. Even when you don't feel like it, you'll find yourself naturally doing it when you're together with other students. You won't understand everything from the start. However, it depends on how much time you invest and how much you review. Even after completing this course, you need to keep reviewing and studying. Instead of fear of coding tests, I gained confidence that "if I do this consistently every day, I can pass coding tests too." If anyone has similar concerns as mine, I recommend challenging yourself with the mindset of "let's go crazy about algorithms and coding tests" for the nearly 2-month period!!

There are many things you need to know for coding tests that you might miss if you don't look into the details carefully, so it was great that you explained them in an easy-to-understand way. I think I really needed a lecture like this, but it wasn't easy to find. It's been very helpful. Thank you.

The instructor teaches step by step in a kind manner.

The algorithm principles were explained with illustrations, making them easy to understand and memorable! The materials were also well-organized, which made them great for review.

I used to study for coding tests alone, just solving problems endlessly, but my skills weren't improving and I kept going in circles, which gradually weakened my motivation. When I tried to start studying again, I didn't feel confident that I could improve my skills by just solving problems alone as before, and I thought I needed a change, so I decided to take this course. While taking the course, starting from the really fundamental concept of time complexity that I should have been thinking about, I realized there were many things I had been missing, and as I addressed these one by one, even the problems I had solved before looked different, and I think it was really great that I could learn how to think about solution methods!

I love it so much
