Books
Use books when a topic needs durable understanding: databases, statistics, machine learning, system design, and engineering practice.
Resources
Preparation resource hub
A structured index for choosing the right type of reference while learning, practicing, and following a roadmap.
Library
Choose by study need
Use each category for a specific gap: depth, walkthroughs, practitioner context, implementation examples, or repetition.
YouTube
Use video when a visual explanation helps with SQL, probability, ML foundations, deep learning, cloud, or LLM applications.
Blogs
Use practitioner writing for production tradeoffs, incidents, architecture decisions, evaluation lessons, and engineering judgment.
GitHub repositories
Use repositories to inspect concrete examples of pipelines, model training, RAG systems, agents, APIs, and interview collections.
Practice platforms
Use practice platforms for SQL drills, coding fluency, ML cases, system design prompts, and interview exercise repetition.
How to use
Use resources with a defined purpose
Select one resource type for the current study gap, then return to learning pages, interview questions, or a role roadmap.
