5. Interview Templates

This section points to interview templates and cheat sheets for system design and low-level design interviews.

Contents

All template files live in the interview-templates folder:

• HLD Template — Step-by-step high-level design interview guide (45–60 min)

• LLD Template — Low-level design checklist and approach

• Capacity Estimation — Back-of-envelope QPS, storage, bandwidth

• Trade-offs Cheat Sheet — Quick reference for common trade-offs

See also SYSTEM_DESIGN_INTERVIEW_FRAMEWORK.md at the repo root for how to run the interview (clarify → estimate → HLD → bottlenecks → trade-offs → deep dive → scaling/failure).
