System Design Interview Prep for Beginners (Full Course)

🧪 System Design Free Labs: https://kode.wiki/4qQ4dHw System design interview prep for absolute beginners, built around one framework you can reuse on any question. Most candidates fail for a reason that has little to do with how much tech they know. They start drawing boxes before the problem is even clear, then run out of time on the wrong system. This course fixes that with a six-step framework that turns a vague prompt like "design a URL shortener" into something you can finish in 45 minutes. Then the framework gets applied to four real interview problems, each hiding the exact trap the interviewer is quietly watching for. 📚 What you'll learn: 1️⃣ The six-step framework that stops you from building the wrong system under pressure 2️⃣ How to Design a URL shortener that survives a link going viral (caching, hotkeys, 301 vs 302) 3️⃣ How a Rate Limiter really works, and why the token bucket beats fixed and sliding windows 4️⃣ How to build a Notification System where a duplicate SMS almost never reaches the user 5️⃣ How a News Feed loads in under a second, and the celebrity problem that breaks the naive design 🧪 System Design Hands-on Labs: https://kode.wiki/4qQ4dHw 🧩 System Design Playlist: https://www.youtube.com/watch?v=340IofBEaW8&list=PLPOrzEadD7Ew ⏰ Timestamps: 00:00:00 - Introduction to System Design Interview Prep 00:00:40 - How to prepare for System Design Interview? 00:02:00 - What Interviewers Actually Expect? 00:05:18 - The Six-Step Framework 00:08:19 - The first 5 Minutes - Clarifying Questions 00:14:50 - Problem 1: Design a URL Shortener 00:39:49 - Interview Questions in URL Shortener 00:42:49 - Lab: Build the URL Shortener 00:43:28 - Problem 2: Design a Rate Limiter 01:09:19 - Interview Questions in Rate Limiter 01:13:57 - Lab: Build a Rate Limiter 01:14:15 - Problem 3: Design a Notification System 01:52:12 - Interview Questions in Notifications System 01:57:39 - Lab: Build a Notification System 01:58:00 - Problem 4: Design a News Feed 02:35:13 - Interview Questions in News Feed 02:45:00 - Lab: Feed Fan-Out 🔔 Subscribe for more system design and DevOps interview prep #SystemDesign #SystemDesignInterview #KodeKloud #URLShortener #RateLimiter #NotificationSystem #NewsFeed #DistributedSystems #Caching #Redis #Kafka #InterviewPrep #SoftwareEngineering #Backend #Scalability
