How does an AI mock system design interview work?

You are paired with an interactive AI agent that simulates a real engineering manager. It asks architectural questions, evaluates your system design choices in real-time, and provides immediate, comprehensive feedback to help you improve.

What's the difference between Free and Pro?

Free includes basic AI interview practice, interactive whiteboard. PRO gets detailed interview analysis, readiness score with trends, company-specific questions (Google, Meta, Amazon, etc.), all previously asked questions.

How does the AI feedback work?

Our AI analyzes your diagram and responses, then highlights trade-offs, bottlenecks, capacity considerations, and failure scenarios. You'll get concise critique and suggested improvements after each answer. PRO users get detailed analysis and insights after each session.

What topics do the interview questions cover?

Topics include high-level design, scalability, data modeling, caching, sharding, consistency models, messaging systems, storage, observability, and more. Difficulty adapts as you improve.

Is my data and architecture kept private?

Yes. Your sessions and diagrams are private to your account. We follow strict security practices and never share your designs. You can also export and delete your data at any time in settings.

Can I cancel my Pro plan anytime?

Absolutely. You can cancel anytime from your account. You'll retain Pro access until the end of your current billing period and then automatically move to the Free tier.
