🌟 Key Features

📚 Multi-Domain Assessment System

Our assessment platform implements a versatile multi-domain system designed to evaluate candidates across different specializations. The system has been architected to handle three distinct domains while maintaining flexibility for future expansions.

Question Types

1. Multiple Choice Questions (MCQs)

   • Advanced randomization and time-tracking features
   • Categorized by difficulty level and topic
   • Prevents backward navigation
   • Question-specific time limits

2. Descriptive Answers

   • Rich text editor with auto-save functionality
   • Markdown formatting support
   • Response length and writing time tracking
   • Content preservation features

3. Domain-Specific Challenges

   • Technical candidates: Live coding exercises
   • Design candidates: Portfolio submissions with process documentation
   • Marketing candidates: Video presentations of campaign strategies

🔐 Advanced Biometric Authentication

1. Face Registration Process

   • Multiple facial angle capture
   • Different lighting condition support
   • Reliable reference profile creation

2. Pre-exam Verification

   • Thorough identity verification
   • Advanced facial recognition algorithms
   • Real-time profile matching

3. Continuous Monitoring

   • Periodic face matching
   • Session security maintenance
   • Prevention of candidate substitution
