Inspiration

Interview prep is stressful and boring. We wanted to make it real, interactive, and fun with AI voice agents.

What it does

PrepWise lets you practice mock interviews with an AI voice agent, get instant feedback, and track your progress — all in a sleek, modern dashboard.

How we built it

Next.js for frontend + backend Firebase for auth & data TailwindCSS + shadcn/ui for styling Vapi AI for real-time voice interviews Google Gemini + Zod for smart, structured feedback

Challenges we ran into

Handling real-time voice integration Getting structured AI feedback right with Zod Designing a smooth, responsive UI that feels natural

Accomplishments that we're proud of

Built a working AI-driven interview simulator Clean, responsive UI/UX Actionable AI feedback that actually helps

What we learned

Real-time AI voice integration is tricky but awesome Schema validation with Zod saves headaches Balancing performance + design is key

What's next for PrepWise
