## 🐛 Troubleshooting

### **🔧 Common Issues & Solutions**

#### **❌ API Key Errors**
```bash
# Error: "OpenAI API key not found"
# Solution: Check environment variables
echo $OPENAI_API_KEY
export OPENAI_API_KEY=sk-proj-your-key-here

# Error: "Rate limit exceeded" 
# Solution: Wait or upgrade API plan
# Fallback: Uses Anthropic automatically
```

#### **🌐 Web Scraping Issues**
```bash
# Error: "Failed to scrape LinkedIn"
# Solution: Use Firecrawl or copy-paste job description
export FIRECRAWL_API_KEY=fc-your-key-here

# Error: "Selenium WebDriver not found"
# Solution: Install ChromeDriver or use Firecrawl
pip install webdriver-manager
```

#### **📄 PDF Processing Problems**
```bash
# Error: "PDF parsing failed"
# Solution: Try alternative methods
pip install --upgrade PyPDF2 pdfplumber
# Or use text input instead of file upload
```

#### **🔒 Authentication Issues**
```bash
# Error: "Google OAuth failed"
# Solution: Check credentials and setup
export GOOGLE_CLIENT_ID=your-client-id
export GOOGLE_CLIENT_SECRET=your-secret

# Bypass: Use development mode
export DEVELOPMENT_MODE=true
export AUTH_ENABLED=false
```

### **📊 Performance Debugging**

#### **🕐 Slow Response Times**
```python
# Check metrics.py for performance monitoring
import metrics
metrics.log_metric("analysis_time", {"duration": 45.2})

# Common causes:
# 1. API rate limits → Use multiple keys
# 2. Large PDFs → Limit page count
# 3. Complex jobs → Simplify analysis
# 4. Network issues → Check connectivity
```

#### **💾 Memory Issues**
```python
# Monitor memory usage
import psutil
print(f"Memory: {psutil.virtual_memory().percent}%")

# Solutions:
# 1. Restart application regularly
# 2. Clear temporary files
# 3. Increase server memory
# 4. Optimize PDF processing
```

### **🔍 Debugging Tools**

#### **📝 Logging Configuration**
```python
import logging
logging.basicConfig(level=logging.DEBUG)

# Enable detailed logging
export GRADIO_DEBUG=true
export PYTHONPATH="."
```

#### **🧪 Test Suite**
```bash
# Run comprehensive tests
python test_interview_guide.py
python test_firecrawl_integration.py

# Individual component tests
cd tests/
python -m pytest test_*.py -v
```
