🎯 Crack Data Science Interviews Like a Pro

Interviews can be tough, but preparation makes all the difference! Here’s how to ace your next one:

📌 Technical Skills to Master

🔹 Python, SQL, and Probability & Statistics

🔹 Machine Learning Algorithms (Linear Regression, Decision Trees, Neural Networks)

🔹 Hands-on experience with Pandas, NumPy, Scikit-learn

🔹 Working with real datasets from Kaggle and UCI ML Repository

📌 Common Data Science Interview Questions

1️⃣ What is overfitting? How do you prevent it?

2️⃣ Explain bias-variance tradeoff.

3️⃣ What are precision, recall, and F1-score?

4️⃣ How do you handle missing data in a dataset?

5️⃣ How would you deploy a machine learning model into production?

📌 Behavioral Questions

✔ Tell me about a challenging data science project you worked on.

✔ How do you explain a complex ML model to a non-technical audience?

✔ Describe a time you had to deal with messy data.

💡 Pro Tip: Practice solving coding problems on Leetcode and HackerRank. Also, participate in mock interviews to build confidence!
