  • Concentrated attack on frequently appearing topics such as arrays, hash maps, trees, graphs, recursion, DP, etc.

  • Practice articulating thoughts in a real-world interview environment.

  • FAANG, Coupang, Toss, Karrot, Banksalad, etc. Technical Interview Common Points

Coding Interview Survival Strategies from a Silicon Valley Engineer

  • Why do I study algorithms so much but feel at a loss during interviews?

  • You can solve the problem, but are you speechless in front of the interviewer?

  • You know about time complexity, but are you confused about how to approach the actual problem?

  • Are you struggling with the same problem over and over again, but finding yourself approaching it in a different way?

  • Have you ever lost your sense of flow just by hearing an English question?

  • Have you ever felt like you got the answer right but didn't know why you failed?


  • Have you ever tried training that demonstrates your 'way of thinking'?

  • You prepared hard, but do you always feel regretful after the interview?


Stop simply memorizing the correct answers and start learning how to think .

The most important thing in a coding interview is not flashy tricks, but a deep understanding of the basics .

Data structures, algorithms, problem solving - if you have a solid foundation, you won't be shaken by any problem that comes up.

If your basics are weak, you will quickly crumble when faced with unfamiliar problems, but if your fundamentals are solid, you will be able to logically solve any question.


Learn frequently asked problem types and solving strategies with practical examples.

  • What can you learn?

    • Core patterns that frequently appear in coding interviews (Two Pointers, DFS/BFS, Heap, etc.)

    • A communication strategy that expresses the flow of thoughts in words.

    • Optimization solution considering time complexity and space complexity


  • Where can it help?

    • Technical Interviews with Big Tech (FAANG) and Domestic and Foreign IT Companies

    • Preparing for a Career Change

    • Developing the ability to apply algorithm skills in real-world situations

  • Recommended for

    I had an interview scheduled and felt overwhelmed when I started doing LeetCode again, but the lectures were very helpful for reviewing data structures and algorithms. Old memories are gradually coming back to me.

      Hi Rorschach, Glad the lecture was helpful. I'll keep supplementing it to make it even more useful.

    Honestly, I used to study coding with the mindset of "just work hard and it'll work out," but after taking this course, my thinking completely changed. I learned for the first time what "strategic preparation" really means. Interview problems that I couldn't grasp at all when studying from books alone now I have this sense of "ah, if they ask this way, I should solve it this way!" And what was really genuine was... They covered everything including overseas company interview processes, which gave me the confidence to think "maybe I should try it once too!" 😆

    Good points: 1. Overall, it contains most of the content related to algorithms, making it a great lecture for reminders. 2. I feel myself getting more familiar with algorithm-related terms by encountering them in English. 3. It became an opportunity to get familiar with algorithm concepts in English and encounter LeetCode problems. 4. The practical problem-solving section is also great because, although short, I can quickly solve problems myself and then check the instructor's solutions to see improvements. Problems that look difficult on the surface are explained easily, which is very helpful. Since it's said to be continuously updated, awesome! 🥳 I'm leaving improvement suggestions for better lecture quality. @ Improvement points 1. Increase font size for text in some videos 2. Repetitive use of the phrase "we" # Will continue adding

    Thanks to this lecture, I learned not just to "work hard," but how to prepare strategically. If you're considering overseas employment, this lecture could be your starting point.

      At first, overseas employment felt vague, but after taking this lecture, concrete preparation methods became clear in my mind. It wasn't just a lecture about solving coding problems; it taught in detail how to actually think and approach things, which was incredibly helpful. In particular, explaining the types of problems frequently encountered in overseas interviews and strategic approaches gave me confidence. I believe this lecture would be sufficiently helpful for those preparing for domestic employment, and if you are considering overseas as well, I highly recommend it. Above all, the realistic advice provided by someone who directly works in Silicon Valley was a great source of strength.
