AI-Powered Automated Interview System
A sophisticated, enterprise-ready interview automation platform that conducts human-like conversations using LangGraph and Claude AI.
đ Key Features
1. Intelligent Interview Flow Engine
Built on LangGraph's state machine architecture, the platform orchestrates complex, multi-turn conversations that adapt in real-time based on candidate responses.
Stateful conversation management â maintains full context across the interview
Dynamic question routing â automatically determines the next best question
Configurable follow-up depth â set how deep the AI should probe each topic (0-5 follow-ups)
2. Two Interview Modes
Screener InterviewExit InterviewAssess candidate qualificationsGather departing employee feedbackJob fit & experience questionsRetention insights & company cultureAvailability & salary expectationsManager relationships & improvement areasWork arrangement preferencesFuture recommendations
3. Multiple Question Types
đ Number Scale (1-10) â Rate experiences with smart validation
â
Yes/No â Natural language understanding ("yeah", "nope", "absolutely")
đ Short Answer â Quick factual responses
đ Long Answer â Detailed feedback with AI follow-ups
đ Single Select â Multiple choice with fuzzy matching
đ± Phone Number â International format validation
4. AI-Powered Response Analysis
The platform analyzes every response in parallel for:
Concern Detection â Flags EEOC issues, safety incidents, harassment reports
Response Quality â Determines if answers need clarification
Contextual Understanding â Recognizes off-topic or incomplete responses
5. Empathetic, Human-Like Conversations
AI-generated acknowledgments that validate and show understanding
Contextual follow-up questions specific to what the candidate said
Warm welcome and closing messages tailored to interview type
6. Multi-Language Support
Automatic translation for non-English responses â candidates can respond in their preferred language while the system processes everything in English.
7. Smart Validation & Re-prompting
Invalid responses trigger friendly re-prompts:
"I need a number between 1 and 10. What would you say?"
"Could you answer with yes or no?"
"Please choose one of these options: Remote, Hybrid, On-site"
8. Concern Handling Protocol
When sensitive content is detected, the system responds with pre-approved, compliant messaging:
EEOC Issues â Acknowledges, provides HR reporting options
Safety Incidents â Directs to proper reporting channels
Off-Topic â Gently redirects back to the interview
đ» Developer Experience
