Clarify the problem
Establish users, constraints, scale, quality attributes, and ambiguous requirements before choosing components.
Frontend system design interview
Design the frontend system on a live, AI-aware whiteboard.
Practice frontend system design with an automatically generated brief, interactive architecture board, and evidence-based follow-up questions.
Make the important signals observable.
Make architecture visible
Create components and connections on the board while explaining responsibilities and data flow.
Defend tradeoffs
Discuss performance, reliability, observability, security, accessibility, and evolution.
A focused path from setup to evidence.
- 01
Generate the brief
The AI prepares a framework-agnostic system-design problem for the selected level and focus.
- 02
Build the architecture
Use the interactive board to map components, boundaries, connections, and important flows.
- 03
Review the evidence
Receive feedback only when the conversation and developed board contain enough real architecture evidence.
Why this format
Architecture before framework preference
The brief should describe a product and its constraints, not prescribe React or another framework. This keeps the interview focused on boundaries, data, failure modes, and scalable frontend decisions.
What to expect
Do I need to draw a perfect diagram?+
No. The board exists to make your model discussable. Clear responsibilities and connections matter more than visual polish.
Why can’t an empty board produce a score?+
A reliable report needs developed architecture evidence, not a guess based on a short session.
Is the task tied to React?+
No. Frontend system design is framework-agnostic unless the scenario makes a specific constraint relevant.
