一覽

System design interviews test your ability to architect large-scale systems (designing Twitter, Netflix, Uber, etc.). Covers scalability, reliability, fault tolerance, consistency, availability, and technology choices. Used by tech companies for senior engineer and staff engineer interviews. Time to learn: 12–16 weeks of focused prep. Critical for landing high-paying roles at top tech companies.

什麼是 System Design Interview

A system design interview is a technical interview where you're given a vague requirement (e.g., "Design a video streaming platform like Netflix") and must propose a system architecture. You clarify requirements, propose solutions, discuss tradeoffs (consistency vs. availability, latency vs. throughput), and defend your choices. It's about thinking like an architect, not a programmer: load balancing, databases, caching, messaging, monitoring, and scaling.

❓ 常見問題

What's the format of a system design interview?
1–2 hours. Interviewer gives a vague requirement (e.g., 'Design Twitter'). You clarify requirements, propose architecture, discuss tradeoffs. Collaboration matters more than perfect design.
Is there a 'right' answer?
No. Interviewers test your reasoning and communication, not knowledge of The Correct Design. Multiple solutions are valid; justify your choices.
How much code is needed?
Almost none. System design is about architecture, not implementation. Pseudocode is fine. Focus on diagrams and reasoning.
What's the most important skill?
Communication. Talk through your thinking. Ask clarifying questions. Explain tradeoffs. A mediocre design communicated clearly > brilliant design explained poorly.
How do I practice?
Interview prep sites (LeetCode, DesignGurus) have problems. Do 20–30 past questions. Then do mock interviews with friends or engineers.
