Hiring Agent Compliance Report
Project Overview
This report provides a comprehensive overview of the hiring agent project, its implementation details, and compliance considerations under the EU AI Act. The project implements an AI-powered hiring assistant that helps evaluate job applications against job offers using multiple AI models and evaluation frameworks.
System Architecture
The hiring agent system consists of several key components:
-
Data Collection and Processing
- Applicant characteristics extraction
- Job offer analysis
- Dataset generation and management
-
Model Pipeline
- Extraction model for parsing applications and job offers
- Comparison model for evaluating matches
- Guardrail model for compliance checks
- Human-in-the-loop review system
-
Evaluation Framework
- Automated testing
- Batch evaluation capabilities
- Performance metrics tracking
Data Flow and Artifacts
The system implements robust data management practices with comprehensive tracking:
-
Dataset Generation Process
- Job offers are processed from PDFs
- Applicant characteristics are generated with controllable bias factors
- Applications are synthesized based on job requirements
- Datasets are versioned and tracked in W&B and Weave
-
Applicant Characteristics Distribution
- Gender, age, nationality distribution is monitored
- Quality scores are calculated and tracked
- R-score measures overall dataset quality and balance
Model Performance
The project tracks performance of both pre-trained and fine-tuned models:
-
Fine-tuning Metrics
- Training loss and learning rate are monitored
- Custom Llama 3.2 models are trained for comparison tasks
- Evaluation metrics track model improvement
-
Evaluation Results
- Decision accuracy is measured across models
- Reasoning quality is assessed
- Performance comparisons guide model selection
EU AI Act Compliance
The system is designed to comply with the EU AI Act requirements:
-
Transparency Requirements
- Clear disclosure of AI system capabilities
- Human oversight mechanisms
- Explainable decision-making process
-
Risk Management
- Regular bias assessment
- Performance monitoring
- Incident response procedures
-
Bias Assessment
- Decision distribution by gender is monitored
- Age group analysis ensures fairness
- Nationality distribution is tracked
-
Hallucination Detection
- Advanced guardrail system detects hallucinations
- Automatic escalation to human review
- Comprehensive tracking of hallucination rates
Data Governance
The system implements robust data governance practices:
- Data Versioning
- All datasets are versioned with W&B Artifacts and Weave
- Each dataset artifact contains comprehensive metadata
- Dataset lineage is tracked throughout the system
Dataset Lineage Example
import weave# Example of dataset lineage trackingdataset = weave.ref('weave:///wandb-smle/e2e-hiring-assistant/object/evaluation_dataset:latest').get()# Characteristics source tracked in metadatacharacteristics_source = artifact.metadata['characteristics_source']
GDPR Compliance
The system is designed with privacy by design principles:
- Personal data is pseudonymized
- Data minimization principles are applied
- Clear purpose limitations for data usage
- Data is stored securely with appropriate access controls
Human-in-the-Loop Oversight
The system implements a comprehensive human-in-the-loop review mechanism:
-
Expert Review Process
- Triggered automatically when hallucinations are detected
- Can be enabled for all decisions
- Captures expert feedback and reasoning
-
Expert Review Statistics
- Expert review trigger rate varies by model
- Decision change rates are tracked
- System learns from expert feedback
Technical Safeguards
The system implements multiple technical safeguards:
-
Guardrail System
- Hallucination detection
- Content policy enforcement
- Automatic escalation to human review
-
Monitoring
- Real-time performance monitoring
- Drift detection
- Alerting mechanisms
Future Improvements
Planned improvements to enhance compliance and performance:
