I am building an end-to-end interview simulator where candidates register, pay, and complete a fully automated, AI-driven interview that zeroes in on job-specific skills. The system must: • Guide users through sign-up and payment (Stripe or similar). • Present questions on screen and allow answers either by typing or by recording voice; speech-to-text should capture spoken replies accurately. • Select the next question through a blend of pre-defined sets and real-time generation so that every prompt feels tailored to the previous response. • Conclude with an instant, clearly formatted feedback report sent to the candidate and a duplicate emailed to me. After the report is issued, the platform should let users purchase and schedule a one-hour coaching session on an integrated calendar. Acceptance criteria 1. Responsive web app with secure login, payment, interview flow, and admin dashboard. 2. Question engine switches seamlessly between scripted and dynamically generated prompts. 3. Voice capture works in modern browsers; transcripts appear for review. 4. PDF/HTML feedback reports include scoring, strengths, and improvement tips. 5. Scheduling module confirms bookings and syncs with Google Calendar (or similar). 6. Full source code, setup instructions, and a short demo video complete the delivery. Technologies are flexible—React, Node, Python, or comparable stacks are all welcome—as long as the final product is stable, intuitive, and ready for real candidates.
