This is the core document providing a comprehensive guide to Meta's data science interview process. It covers:

• Introduction: Overview of Meta's interview process and values.
• Foundational Knowledge & Skills: In-depth review of essential topics including statistics 📊, probability 🎲, SQL 📑, and data analysis with Python/R 🐍.
• Interview-Specific Preparation: Guidance on tackling each stage of the interview process, from technical screens to behavioral questions.
• Analytical Execution/Case Study Interview: Deep dive into techniques for data analysis, hypothesis generation, and communication.
• Analytical Reasoning/Product Sense Interview: Strategies for clarifying problems, developing product sense, defining metrics, and designing experiments.
• Resources & Communities: Curated list of learning materials 📚, online communities 🧑‍🤝‍🧑, and helpful resources.

2. Statistics and Probability Examples (Statistics-Probability-Example-Questions.MD) 💯

This file provides detailed examples and solutions to common statistics and probability questions encountered in data science interviews. It covers:

• Descriptive Statistics: Questions on measures of central tendency, variability, and data visualization 📊.
• Probability: Questions on Bayes' theorem, probability distributions, and sampling techniques.
• Inferential Statistics: Questions on hypothesis testing, p-values, confidence intervals, and significance testing.
• Statistical Modeling: Questions on regression analysis, A/B testing, and experimentation.

3. SQL Example Problems (sql-example-problems.md, sql-example-problems.pdf) 📝

This file (available in both markdown and PDF formats) presents a collection of complex SQL problems designed to simulate real-world scenarios at Meta 🌍. The problems cover a wide range of SQL concepts and techniques, including joins, aggregations, subqueries, window functions, and more.
