InterviewIQ
AI interview coaching platform that helps candidates practice role-specific interviews, receive structured feedback, and prepare with more confidence.
The Problem
Candidates often prepare with generic questions and disconnected notes, making it difficult to practice realistic interviews or understand how to improve each response.
The Solution
InterviewIQ turns interview preparation into a guided AI practice experience that generates relevant prompts, evaluates responses, and gives candidates clear next steps before the real conversation.
03
How the AI interview system works
The system combines role context, interview goals, and the candidate's responses to create a focused practice loop.
The candidate selects an interview context and starts a guided practice session.
The AI generates relevant interview questions and follow-ups for that context.
The candidate submits an answer and receives structured feedback on clarity, relevance, and confidence.
The next prompt adapts the practice flow so preparation stays focused on the candidate's gaps.
04
Key features

05
Paystack payment integration
Paystack provides the payment layer for paid interview preparation access, giving the product a clear path from useful free exploration to a monetized coaching experience.
Checkout is handled through Paystack's hosted payment flow.
Payment status is verified before paid functionality is made available.
The integration keeps payment handling separate from the AI practice experience.
06
Technical architecture
The application uses a Next.js and TypeScript frontend with server-side integration boundaries for AI generation and payments.
Next.js renders the interview workspace, question flow, and feedback views.
Server-side routes coordinate requests to OpenRouter AI without exposing provider credentials in the browser.
OpenRouter handles question generation and response evaluation within the interview loop.
Paystack handles checkout and payment verification for paid access.
Impact
Candidates get a repeatable way to practice, identify weak spots, and build confidence with focused feedback instead of relying on one-size-fits-all preparation.
