Crush Every Web Dev Interview. Get A Dream Job. Guaranteed. --- Site Content --- Get Started Now The ULTIMATE Preparation System to Crush Every Web Dev Interview, GUARANTEED. Or Your Money Back. Tired of endless interview failings and missed opportunities? Discover the system that guarantees you'll master any web dev tech concept, ace every interview, and get a job – or I'll refund! Get Dream Job Offer Hey web dev 👋 Please tell me how many job interviews have you failed at? 10? 20? 50+? Remember this super attractive salary that has just slipped away. Shitty feeling 😔 Is this familiar? Endless cycle I failed so many times - I can't even recall. To name a few: April 2024 I failed to get UK remote React Dev job with $4,200/mo only because I couldn't explain what are Portals in React. That's it. One question. May 2024 Another missed opportunity for Russian remote Front End Web Dev role at $3,500/mo. I missed it because I kinda understood HTTP. The keyword is "kinda". So, the word "kinda" - this is what separates dream job getters from endless interview seekers. I can tell you many more stories, but even better if I show a real screenshot from one my unsuccessful interviews from Turing. U.S. based company Let's count a few things... Time Spent Last Week Please recall how many hours did you spend last week on: sending job applications (do you like "Easy apply"? 😄) polishing your LinkedIn registering on job boards Is it 5, 15, 35 hours??? YouTube Tutorial Rabbit Hole How many Youtube videos like this you have watched? How to NOT Fail a Technical Interview How To Pass Coding Interviews Like the Top 1% 5 Coding Interview Tips From A Senior Engineer Was it useful to pass the tech interview? Bookmarked for "Later" How many interview prepping Reddit threads and blog posts have you bookmarked for later? (tell you the secret: the later never comes 🤫) Or do you remember that Github repo containing a curated list of awesome remote dev job lists. With 40k stars and so long that takes 2 lifetimes to scroll to the bottom 🤯 Are you actually going to go thru this repo? Man, from May 2023 to November 2024 (18 months - crazy 🤯) I applied to 1000+ remote and relocation jobs and had dozens of interviews. Name any significant web dev job platform - I had a verified profile there: Turing.com Arc.dev hh.ru relocate.me I conducted so many tests on LinkedIn that platform banned me and suspended my account forever. (the reason: I was connecting 100 recruiters a week, which is the weekly limit. System thought I used a robot). I felt so SICK from the job searching process that I have refused any interview invitation for a while. Remember I mentioned that I had dozens of interviews? . Those resulted into 6 job offers . But not all of them were attractive to me. Still remember this Zoom call on the last round interview with a company that developed Shopify plugin. I thought to myself: "I have ZERO interest in Shopify plugins" The point is it's TOUGH to get a job that clicks with you 100%. MORAL You must perform extraordinary well on your dream job interview, because price is HIGH Before I explain how I solved this problem, just wanted to mention that I cracked the code and got a dream job offer with paid relocation for my family and I. Dream job offer The thing is... For a long time, web devs have been stuck in a loop—boring study habits, basic resources, and way too much information to deal with. You spend hours reading guides, watching videos, and doing practice tasks, but it still feels like something's missing. You get stuck on hard questions and miss opportunities because your skills aren't as sharp or easy to use as they should be. ANSWER You have no working interview preparation SYSTEM Solution Introduction The Flashcard System It helps you cut through the noise and actually learn what matters. It's not just about memorizing facts—it's about really understanding, remembering fast, and building a solid base in every web tech you study. I've taken years of experience and scientific learning methods and turned them into a tool that gives you the right info at the right time. Why Spaced Repetition (e.g. Flashcards) Works The Forgetting Curve We forget most of what we learn within days. Spaced repetition stops this by reminding you just before you forget, locking the memory in. (Ebbinghaus, 1885) Active Recall Instead of rereading notes, you test yourself. Pulling answers from memory builds stronger brain connections and makes learning stick. (Roediger & Karpicke, 2006) The Spacing Effect Hundreds of studies show that spreading study sessions out beats cramming every single time. It leads to higher scores and longer retention. (Cepeda et al., 2006) Brain Connection Strength Every recall session strengthens the pathways between your neurons through a process called long-term potentiation . (Bliss & Lømo, 1973) Desirable Difficulty Spaced learning feels harder than cramming—but that challenge is exactly what makes it more effective. (Bjork & Bjork, 1992) Efficiency Boost Learn more in less time. Research shows spaced repetition can cut study time by 30–40% while helping you remember longer. (Cepeda et al., 2008) Key Benefits What if you could... Unlock the hidden secrets to answer even the hardest tech questions (e.g. JavaScript closure) and impress interviewers with how clear you explain things. Bypass the endless tutorial rabbit hole and get straight to the core concepts that actually land you the job Eliminate the crippling fear tackling tough concepts by building a rock-solid foundation and remembering them right when you need Gain an unfair advantage over other candidates by demonstrating a depth of knowledge they can only dream of Start Your Learning Journey Inside App Stay on top of your learning with easy, smart quiz tools.

You won't just know what the answer is, but why it's the answer , building a robust, conceptual understanding that lasts Get Your Unfair Advantage Who Is This For This system was built for web developers who are serious about leveling up their career and finally cracking technical interviews. If you see yourself in any of these, you're in the right place: Perfect For... Entry-Level Developers Students, bootcamp grads, or self-taught devs looking to land their very first web dev job with confidence. Mid-Level Developers Aiming for promotions, better roles, or higher salaries by mastering advanced concepts and interview techniques. Senior Developers Switching Tech or Roles Needing to quickly upskill in a new stack while staying sharp and credible in interviews. Developers on a Tight Timeline With interviews coming up in days (not months) and needing fast, structured prep that gets results. Continuous Learners Devs who want to stay sharp, reinforce fundamentals, and be "always interview-ready" without cramming. If you're motivated, coachable, and willing to put in short, consistent practice, this system will give you an edge in every interview. Not Right For... This system isn't for everyone. It's probably not a fit if you: Expect a "magic button" that lands you a job without any effort. Aren't willing to practice regularly, even 10–15 minutes a day. Already have years of FAANG-level interview prep resources and don't feel the need to sharpen your fundamentals. Are looking for a complete coding bootcamp or a beginner's "learn programming from scratch" course (this is for practicing, not learning basics). Don't actually plan to interview for web development roles anytime soon. This helps you see if the system is right for you — and if it is, you’ll start seeing results faster than you ever expected. Important I can't promise results unless you practice at least 20–25 minutes a day for the EXACT tech stack your interview is about. If you're not ready to do that, it's better not to buy. That way, we both stay happy and stress-free. Listen To What My Students Say Words of my students. From my courses at ClickBuilders and live events I recently completed the "Prompt. Build. Ship" course and was thoroughly impressed! The course is well-structured, the material is delivered clearly and engagingly, and the examples are genuinely inspiring. I especially appreciated how it covers the nuances of working with different types of AI — from text generation to image models. I started applying what I learned to real tasks during the course and immediately noticed a significant improvement in the quality of my prompts. Huge thanks to Ilyas Seisov for his thoughtful approach, practical exercises, and ongoing support. Highly recommended for both beginners and advanced users. Five stars, well deserved! Rustam Guseynov The "Prompt.Build.Ship" course by ClickBuilde.rs is a great option for anyone who wants to learn how to create effective prompts for AI models like ChatGPT. The material is presented clearly and step by step, starting from the basics and moving to more advanced techniques. What makes the course especially valuable is its practical approach—you can immediately apply what you learn and build your own projects. It doesn’t require any programming skills, so it’s perfect for beginners. The active community is also a big plus, offering support and helpful advice. Overall, the course is inspiring and provides a strong foundation for anyone interested in working with AI. Emir Arrykov I just finished the "Prompt. Build. Ship." course, and honestly, it was super practical. Before this, I’d usually spend way too much time stuck debugging or overthinking how to structure my code. What really made a difference was actually using AI tools on real projects throughout the course. There was one part where I couldn’t quite get a database query to work right. The course showed how to use AI to come up with better ways to optimize it, and that helped me figure it out way faster than I would’ve on my own. The biggest thing I learned is that getting useful answers from AI is all about asking the right questions. It takes a bit to get the hang of it, but once you do, it’s cool to see how AI can fit into your coding workflow. Definitely a helpful experience. Said Rozmamedov Solid intro to AI! I’m more of a no-code Bubble user, but this helped me get what’s possible with AI (ex: prompt engineering ✅). Appreciate how it made things easy to understand. Ylyas Kudratullayev I have attended many events where Ilyas Seisov performed, and I can say that his work helps the younger generation develop faster and inspires them to seek new knowledge. I was especially impressed by his professional skills — the way he presents information and engages with the audience. His speeches are never boring they are always lively, interesting, and truly motivating.. Owezov Resul First of all, I’d like to say that everything was very clear, even for an inexperienced developer. I really enjoyed the interactive session, where you could comfortably ask anything about prompt engineering. What stood out the most was learning how to use prompts not like a shovel, but like an entire dump truck. All three key points turned out to be truly practical tools. I especially appreciated that the speaker clearly knew what they were talking about and, being a full-stack developer, could explain anything. I’m very grateful for this event and wish continued success in all future projects and endeavors. Rustem Nuryyev Ilyas Seisov programming course is outstanding. Clear explanations, practical examples, and real-world tasks make learning both easy and exciting. I gained valuable skills and confidence. Highly recommended for beginners and professionals alike! Serdar Orazdurdyyev Special shoutout to Ilyas Seisov for his talk on AI in Web Development — super practical and inspiring! He broke down how AI can be integrated into the frontend & backend workflow, automate repetitive tasks. Got me thinking about new ways to speed up my own projects! 💻🤖 Bezirgen Shayymov Pass Your Next Interview Meet The Creator Hi 👋, I'm Ilyas Seisov. I'm web dev just like you. I build websites and web apps every day just like you. "After dozens of failed interviews I've developed approach to scratch my own itch. It worked. Now I decided to share it with you."
