BLinterview

About the Project

AI-powered platform for interview practice through voice conversation and text chat based on ElevenLabs and OpenAI GPT-4. This project was designed with an approach emphasizing process measurability, ease of use, and implementation reliability, capable of delivering real impact on work efficiency and service quality. This product was developed as a prototype to open opportunities for AI conversation-based derivative project ideas.

Key Features

• Interactive AI Voice Calls — Users can practice interviews in conversation simulations that resemble real situations.
• User Dashboard — Practice session progress can be monitored for continuous evaluation and improvement.
• Transcript Management — Conversation history is available as material for reflecting on answer quality and communication.

Challenges & Solutions

• Challenge: ElevenLabs integration must maintain smooth two-way conversation flow. Solution: Communication pipeline is optimized so voice interactions remain responsive and natural.
• Challenge: Agent must consistently ask things relevant to interview scenarios. Solution: Multi-level prompt configuration is applied to keep question focus according to simulation objectives.
