CS Fundamentals is a curated collection of study materials designed to help you prepare for technical job interviews. It bundles together notes, cheatsheets, and interview question banks for the core computer science subjects that employers typically test, saving you the time of hunting down resources across the internet. The repository is essentially a digital library organized into folders by topic. You will find materials for Data Structures and Algorithms (DSA), databases and SQL, computer networks, operating systems, object-oriented programming, system design, and software engineering. Each folder contains a mix of comprehensive study notes, quick-reference cheatsheets, and lists of frequently asked interview questions. There are also general job-hunting resources at the top level, including a cover letter template, a list of companies hiring fresh graduates, and AI prompts to help you practice for interviews. This collection is aimed primarily at students and recent graduates preparing for campus or off-campus placement seasons. If you are a fresh graduate brushing up on database concepts before a technical round, or a self-taught programmer trying to fill gaps in your computer science knowledge before applying to a major tech company, these materials give you a structured starting point. The DSA section, for example, includes both a learning resource guide and a popular interview prep sheet with solutions, while the OOPs section covers how object-oriented principles apply across Java, Python, JavaScript, and C++. It is worth noting that this is an aggregation project rather than original content. The creator has gathered these documents from various sources across the internet and explicitly notes that they do not claim ownership of the individual files. Because of this, the depth and format of the materials vary from folder to folder, ranging from handwritten-style notes to full textbooks and quick-reference cheatsheets.
