🚀 Day 21: Mastering the Whiteboard Coding Round ✍️

Welcome to Day 21 of the 30-Day Placement Series! Today, we’re diving into the whiteboard interview, one of the most crucial aspects of coding rounds. Whether in-person or virtual, how you approach and communicate your solution is key.

📋 Step 1: Understand the Problem
Start by repeating the question to confirm your understanding. Write it down on the whiteboard—this serves as your reference during the problem-solving process.

🧠 Step 2: Design the Logic
Before coding, take a moment to visualize your solution:

🔎 Draw diagrams or structure arrays, labels, etc.
🖋️ Write sample input/output to understand behavior.
📐 Break down the algorithm using flowcharts or pseudo-code. This helps show your thought process.
💻 Step 3: Implement the Solution
Once you're aligned with the interviewer, begin coding clearly:

✨ Start from the left of the board, breaking your solution into smaller functions (e.g., sorting or finding duplicates).
🛠️ If unsure, ask for clarification.
📝 Step 4: Test Your Code
Testing is essential:

💬 Walk through your code, explaining your logic and edge cases like null inputs, empty arrays, and negative numbers.
🧪 Test with sample inputs and validate edge cases.
🔄 Step 5: Communicate with the Interviewer
Your communication is just as important as the solution:

🤝 Explain your thought process clearly.
🕵️‍♀️ Be open to feedback and new approaches.
💡 Stay confident, but ask for clarification if needed.
🎯 Key Takeaways
Clarify the problem first and keep it visible.
Use diagrams and break problems into parts.
Write modular code with reusable functions.
Test thoroughly and ask for feedback.
Communicate clearly throughout the process.
