## Prompt

```text
Help me prepare for a system design interview.

**Target role and level:** [e.g. "senior backend engineer"]
**Company type:** [e.g. "large tech company", "fintech startup", "B2B SaaS"]
**Interview date:** [DATE]
**My background:** [SYSTEMS I'VE BUILT, SCALE I'VE WORKED AT, AREAS I'M WEAK IN]
**Format if known:** [LENGTH, WHITEBOARD OR ONLINE TOOL, WHAT THE RECRUITER SAID]

Give me:
1. **A repeatable framework for the interview hour**, with rough timings: clarify requirements and non-functional needs, estimate scale, define APIs and data model, high-level design, deep dive on 1-2 components, trade-offs and bottlenecks, wrap-up.
2. **Core concepts to review**, prioritized by my weak areas: e.g. load balancing, caching, database choice and sharding, replication and consistency, queues and async processing, rate limiting, idempotency, observability.
3. **8 practice questions** suited to the company type, from easier to harder, each with the 2-3 key trade-offs an interviewer is looking for.
4. **One fully worked example** of a question at my level, showing what I'd say and draw at each stage.
5. **Level signals:** what distinguishes a senior answer from a mid-level one (driving the conversation, quantifying, naming trade-offs, operational concerns).
6. **A day-by-day study plan** up to my interview date.

Then offer to run a mock interview: you play the interviewer, ask one question, let me answer step by step, and give feedback against the framework.
