Next.js Interview Copilot UI Dashboard Design

I am expanding my Interview Copilot app and need a fresh, cohesive user experience built in Next.js. The work breaks down into three tightly-linked screens:

• A front page that instantly previews the dashboard so first-time visitors understand the product at a glance.
• A secure login / signup flow that blends smoothly into the overall style.
• The main dashboard, available to interviewees only, featuring two core functions I have already defined—live statistics & analytics plus a smart interview-scheduling panel.

All screens must align visually, feel intuitive on mobile and desktop, and be coded directly in Next.js with clean, reusable components. Final delivery should include the production-ready React/Next code, any supporting assets, and concise hand-off notes so I can plug the new UI straight into my existing backend.
