Mastering System Design: From Junior to Senior Engineer
The Jump to Senior Engineering
One of the biggest hurdles for mid-level engineers aiming for senior roles is the System Design interview. It tests your ability to think broadly about architecture, scalability, and trade-offs.
Core Concepts to Master
- Scalability: Horizontal vs. Vertical scaling.
- Database Choices: SQL vs. NoSQL, CAP theorem implications.
- Caching: Strategies like LRU, Write-through vs. Write-back.
- Load Balancing: Algorithms and placement.
Structuring Your Answer
- Requirement Clarification: Functional and non-functional requirements.
- Back-of-the-envelope Estimations: Storage, bandwidth, latency.
- High-Level Design: Draw the big boxes (Client, LB, Web Server, DB).
- Deep Dive: Focus on interesting components chosen by the interviewer.
