  • Timer with real-time tracking
  • Multiple test cases
  • Code execution and evaluation
• Feedback Provided:
  • Correctness (test case results)
  • Time management analysis
  • Code structure assessment
  • Complexity detection (O notation)
  • Thinking pattern classification
  • Edge case coverage

10. Career Roadmap Generator (Personalized Paths)

• Input career goal (Frontend, Backend, Full-stack, Data Science)
• Generated Roadmap Includes:
  • Phase-based learning structure
  • Skills breakdown per phase
  • Resource recommendations
  • Estimated timeline
• Adjusts based on user's skill graph

11. Multilingual Bot (Context-Aware)

• Supported Languages:
  • English
  • Hindi (Devanagari script)
  • Tamil (Tamil script)
  • Hinglish (Latin script)
• Auto-detects language from input
• Context-aware responses about:
  • Arrays, Loops, Recursion
  • Time Complexity
  • Programming concepts
• Stores doubt history with topic mapping

12. Low Bandwidth Mode (Performance Toggle)

• Disables heavy animations (Motion/Framer Motion)
• Disables 3D rendering (Three.js)
• Uses static lightweight SVG
• Reduces API polling
• Lazy loads images
• Actually reduces resource usage

📊 Data Structures

User Profile

{
  id: string;
  name: string;
  email: string;
  mobile: string;
  skillGraph: SkillData[];
  cognitiveProfile: CognitiveProfile;
  quizHistory: QuizResult[];
}

Cognitive Profile

{
  averageSpeed: number;
  averageAccuracy: number;
  guessPattern: number; // 0-1
  hesitationScore: number; // 0-1
  impulsivityIndex: number; // 0-1
}

Quiz Result

{
  questionId: string;
  concept: string;
  difficulty: 'easy' | 'medium' | 'hard';
  correct: boolean;
  timeSpent: number;
  confidence?: number; // 1-5
  timestamp: string;
}

🎨 Design Features

Theme

🚀 Key Algorithms

Adaptive Quiz Algorithm

if (lastTwo.allCorrect && lastTwo.allFast) {
  difficulty = increaseLevel(currentDifficulty);
} else if (lastTwo.anyWrong) {
  difficulty = decreaseLevel(currentDifficulty);
}

Cognitive Pattern Detection

// Impulsivity
if (fastIncorrect >= 3) → impulsive pattern

// Hesitation
if (slowCorrect >= 3) → conceptual uncertainty

// Guessing
if (lowConfidenceCorrect >= 2) → lucky guesses

Interview Code Evaluation

// Complexity Detection
nestedLoops → O(n²)
singleLoop → O(n)
binarySearch → O(log n)
noLoop → O(1)
