Udemy – System Design Crash Course: Quick Revision Before Interviews

System design interviews are not about drawing perfect architectures or memorizing patterns. They are about thinking clearly, structuring your answer, and explaining trade-offs under pressure. This course is designed as a system design crash course for last-minute interview revision. If you’ve already studied system design before – but struggle to recall concepts quickly, structure your answers, or stay calm during interviews – this course is built exactly for you.

What makes this course different:

• Short, focused lectures (1–2 minutes each): Every lecture covers exactly one concept, making it easy to revise quickly without mental overload.
• Interview-first approach: Each topic is explained the way interviewers expect you to think – not academic theory, not over-engineering.
• Clear frameworks, not memorization: You’ll learn how to approach any system design question using repeatable mental models.
• A universal system design blueprint: One powerful framework that shows all possible system components and helps you decide what to include – or exclude – based on requirements.
• Trade-off driven thinking: Instead of chasing “perfect” designs, you’ll learn how to justify decisions around scalability, performance, cost, and complexity.

What you’ll revise in this course:

• How to start and structure any system design interview question
• Networking basics, request flow, DNS, load balancers, and CDNs
• Communication protocols like HTTP, REST, WebSockets, gRPC, and GraphQL
• Core architectural patterns: monoliths, microservices, event-driven systems
• State management, caching, queues, and messaging systems
• Database choices, replication, sharding, and storage trade-offs
• Scalability, performance optimization, and reliability fundamentals
• Security basics interviewers expect you to know
• Common system design interview mistakes and red flags

All explained quickly, clearly, and with interview context.

Who should take this course:

• Software engineers preparing for system design interviews
• Developers targeting mid-level to senior roles
• Candidates who have already studied system design and want fast revision
• Engineers who struggle to structure answers under interview pressure

This course is not meant for absolute beginners and does not replace a deep, project-based system design course. It is a revision accelerator, not a fundamentals bootcamp.
