Important Steps to Acing your System Design Interview
1. Get Clear on Requirements Clarify what the user needs, identify constraints, and establish project scope. You can't design a system if you don't know what it needs to do!
2. Make Quick Estimates Calculate rough estimates for key metrics like traffic volume, storage requirements, & bandwidth usage. These will help you narrow down design options & avoid unrealistic solutions.
3. High-Level Design Create an architecture diagram & identify major components of the system. This will give you a framework for your design & help you see how all the pieces fit together.
4. Design Your Database Choose the right database type & create a schema that meets the requirements of the system. A well-designed database is essential for the performance & scalability of your system.
5. Design Core Components Break down your system into smaller components & design each one in detail. Pay attention to the API, data flow, & error handling to ensure each component works smoothly.
6. Scale Your Design Plan for growth & scalability by designing a system that can handle increased traffic & data over time. Consider load balancing, caching, & partitioning to distribute workload efficiently.
7. Resolve Bottlenecks Identify potential bottlenecks in your design and find ways to eliminate them. This may involve optimizing code, adding hardware resources, or changing your architecture.
