Abstract
DevgentAI is an AI-powered interview practice system designed to improve interview preparation through intelligent simulation and real-time behavioral analysis. The platform provides users with realistic mock interview experiences across multiple professional domains while evaluating both verbal and non-verbal communication skills. The system integrates artificial intelligence, computer vision, speech recognition, and real-time analytics to deliver personalized feedback and performance insights.
The frontend is developed using React.js and Next.js, while PostgreSQL (Neon) is used for storing interview sessions and analytics. VAPI AI integration, OpenAI GPT-4, Deepgram Nova-2, and ElevenLabs are utilized for intelligent interview interaction and speech processing. The system provides multi-domain interview preparation, real-time performance tracking, and comprehensive analytics through an accessible web-based platform.
The project aims to democratize access to high-quality interview preparation by providing students, job seekers, and professionals with an intelligent virtual interviewer capable of continuous feedback and improvement tracking.
