Inspiration

I wanted to bridge the gap between theory and real IT interviews. Preparing for technical interviews can be stressful, and candidates often struggle to get human-like, personalized feedback. The idea of an AI-powered interviewer came from observing how repetitive practice and immediate evaluation can drastically improve coding and communication skills.

What it does

A real-time AI-powered interview platform that:

  • Acts like a human interviewer, asking relevant technical questions.
  • Provides instant feedback, scoring answers, and suggesting improvements.
  • Tracks conversation history to tailor follow-up questions.

How I built it

Node.js + Express for the API server, handling real-time requests. React.js for the UI/UX. OpenAI API for evaluating answers.

Challenges ran into

OpenAI API sometimes returned 429 Too Many Requests. I implemented a fallback default question to ensure the app remained usable.

What I learned

Prompt engineering is crucial: crafting clear instructions for AI drastically improves question relevance. Error handling in real-time systems matters; fallback defaults keep the user experience smooth.

What's next for AI Interview Simulator

Add more IT topics (system design, database design, cloud architecture)... and also helping users improve soft skills.
