How to use Fake Client Brief to ace your System Design Interviews (SDI).

The "System Design" Interview

For Senior/Staff integration, companies (Google, Amazon, Meta) ask open-ended questions:
"Design a Multi-Region Disaster Recovery Strategy" or "Architect a PCI-DSS Compliant Payment Gateway".

Our briefs are modeled exactly after these prompts. The AI Client simulates the interviewer probing for holes in your logic ("What happens if us-east-1 goes down?").

How to Practice

Mock Interviews

Pair up with a friend. One person plays the "Client" (reading our System Prompts), the other draws the architecture.
