The Challenge

Identifying core hurdles and technical limitations.

1. AI & UX Integration: Complex Al-driven voice feedback required seamless integration with a responsive web interface to prevent user frustration. 2. User Engagement: Keeping interview simulations realistic yet simple for users of all technical levels while maintaining a "human" feel. 3. Scalable Performance: Ensuring real-time feedback and analytics work smoothly under high user load without any detectable delays or errors. Prepza needed a precise, seamless build that scaled effortlessly without disrupting the core user experience.

The Strategy

How we engineered the breakthrough solution.

• Design System & Clean-UI Principles: We built a modular React component library (buttons, forms, colors, typography) and a step-by-step interview flow to simplify onboarding. Real-time feedback replaced obstructive pop-ups for a significantly cleaner UI. • MVVM Refactor & Performance Tuning: Structured the frontend with React + MVVM-inspired state management for clear separation of concerns. Implemented async voice processing to prevent UI lag during intense simulation sessions. • Robust Regression Safety Net: Automated frontend tests with Cypress ensured feature reliability, while continuous integration checks caught errors before deployment. Real-time monitoring of AI feedback modules maintained high accuracy.
