I came running here after hearing that Mr. Noh published the bible of coding tests🥳 Last year, I conquered the data structure and algorithm concepts and representative problems that felt difficult while taking the All-in-One coding test course, and I grew a lot by systematically and repeatedly solving problems through the Killing Camp. During that process, Mr. Noh's lectures were an incredibly big help, and the Python materials for coding tests provided in the Killing Camp were very helpful for problem solving! And this Coding Test Bible seems to be the final compilation where you can see all those materials, concept explanations, and templates at once. Personally, I love the All-in-One coding test course so much that I'd recommend watching it together, but since this book also has detailed explanations, I strongly recommend thoroughly reading it multiple times to make it completely yours! Participating in the All-in-One coding test course + Killing Camp last year was a major turning point in my career, and thanks to that, I overcame my fear of coding tests and successfully switched to a well-known tech company in the US with a 3x salary increase😊😊 If you have the will and persistence to repeatedly acquire the lecture/book content and representative problems (templates), and solve application problems based on that, you'll definitely feel your skills improving rapidly. Make sure to repeatedly solve problems you've already solved after some time intervals. If you solve about 50 problems repeatedly almost by heart with your eyes closed, it becomes really easy from then on. Since I'm a fan of Mr. Noh's lectures, I wrote this review with fan sentiment and it got long😊😊 In conclusion, I highly recommend building your foundation by repeatedly reviewing this book or lectures, and if you have the capacity, participating in the Killing Camp as well! If you have the will, it will be an investment that's not a waste at all🙌
