InterviewIQ

Inspiration

Students like us constantly find ourselves in interviews — for student organizations, internships, and full-time jobs. We created InterviewIQ because when it matters, you should be ready for the interview.

What it does

InterviewIQ is an AI-powered mock interview platform that generates adaptive interview questions based on a user’s target role and job description.

The system evaluates responses in real time, adjusts difficulty based on performance, and tracks long-term progress across sessions. Users can practice with voice input, hear AI interviewer speech, and view performance analytics on a live dashboard.

How we built it

• Frontend: Next.js + TypeScript + TailWind CSS for the interactive interview experience
  
• Backend: Next.js API routes for session logic and scoring
  
• AI: OpenAI API for question generation, evaluation, and feedback
  
• Memory: Supermemory for long-term performance tracking
  
• Voice: OpenAI Whisper (speech-to-text) + ElevenLabs (text-to-speech)
  
• Deployment: Vercel
  

Challenges we ran into

• Designing adaptive difficulty that feels natural
  
• Managing real-time voice input/output latency
  
• Maintaining consistent session state across the interview flow
  
• Structuring long-term memory for meaningful cross-interview insights
  

Accomplishments that we're proud of

• Successfully integrated ElevenLabs voice interviewer
  
• Built a fully adaptive interview engine
  
• Implemented cross-interview memory tracking
  
• Deployed a working end-to-end product during the hackathon
  

What we learned

• How to design adaptive AI feedback loops
  
• Best practices for real-time voice applications
  
• Prompt engineering for structured interview evaluation
  
• Full-stack coordination under hackathon time pressure
  

What's next for InterviewIQ

• Real-time AI interviewer characters
  
• Tone and confidence analysis
  
• More role-specific interview tracks
  
• Improved analytics and progress insights
  
• Multiplayer/mock panel interview mode
