A collection of Jupyter Notebook-based questions and answers covering data science topics such as SQL, statistics, supervised/unsupervised learning, reinforcement learning, NLP, and system design. It is intended as a quick-reference for interview preparation and for beginners learning basic data science concepts.

Use cases

• prepare for data science interview questions
• quickly review machine learning concepts before an interview
• learn basic data science and statistics concepts as a beginner
• brush up on SQL join types and Spark basics
• review reinforcement learning and NLP fundamentals
• get advice on writing a quantified data science resume

When to choose

• you need a broad, quick-reference review of data science topics before an interview
• you are new to data science and want concise explanations of core concepts
• you want community-contributed Q&A style notes across ML, SQL, and system design

When to avoid

• you want in-depth study material on a specific topic
• you need actively maintained content - the repo is deprecated in favor of 'nail-ml-concept'
• you need runnable production code rather than conceptual notes
