An AI-powered mock interview platform that simulates realistic technical and behavioral interviews — helping users build confidence through repeated, structured practice.

The Problem

Interview anxiety suppresses performance. Many strong candidates fail not because they lack knowledge, but because stress interferes at the critical moment.

---

What It Does

Users select a target role, provide a job description, choose a difficulty level, and enter a timed interview session. The system generates personalized questions tailored to the role and context.

A voice-based AI interviewer asks questions in real time. After each response, structured feedback highlights what was strong, what was missing, and how to improve. At the end, a performance summary surfaces patterns across the full session.

Tech Stack

Frontend - React, LiveKit Components
Backend - Django REST Framework, OpenRouter LLM API
Voice - LiveKit Agents, OpenAI STT/TTS, Silero VAD
Auth - Token-based authentication

Key Features

• Live voice interviews — real-time speech with an AI interviewer via LiveKit
• Personalized questions — generated from job description and agent prompt
• Per-answer scoring — structured feedback with a 1–10 score for each response
• Session summary — overall score and feedback across all answers
• Repeatable sessions — designed for progressive improvement over time

How It Works

1. User creates an interview, selects an agent, and optionally pastes a job description
2. Backend generates questions via LLM and initializes a LiveKit room
3. AI agent joins the room, asks questions via TTS, and captures spoken answers via STT
4. On completion, answers are evaluated by LLM and results are saved
5. User reviews per-question feedback and overall performance score
