How It Works

Six steps. Just like the real thing.

Simulation showing the design brief with problem requirements and constraints

01

Read the Design Brief

Understand the problem statement, requirements, and constraints — just like a real machine coding round.

Design tab with form fields for entities, relationships, interfaces, and extensibility plan

02

Answer Design Questions

Explain your high-level design approach. Get AI feedback on your choices and understand the criticality of changes before moving forward.

03

Implement Your Solution

Write your code and validate against visible test cases. Build incrementally, just like you would in a real interview.

Simulation interface with run tests button for hidden test validation

04

Submit for Hidden Tests

Your implementation runs against edge cases and evolving requirements — not just the sample scenarios you saw.

05

Level Up

Handle new constraints mid-session. Extend your implementation under pressure as requirements evolve.

Simulation report with scores for design, correctness, extensibility, and code quality

06

Get Your Report

Receive a structured report with correctness scores, architectural quality review, and actionable improvement areas.

What Sets This Apart

Built for Serious Prep

Hidden Tests

Edge cases and evolving requirements, not sample I/O.

Code Review

AI evaluates your design decisions, modularity, and extensibility.

Progressive Reqs

New constraints mid-session, just like real rounds.
