Placement Handwritten Notes PDF – DSA, DBMS, OS, Web Dev, OOP & More (Free)
Preparing for placements can be overwhelming. From coding rounds to technical interviews, you’re expected to know DSA, DBMS, Operating Systems, Web Development, OOP concepts, and even basics of Cloud & ML. To make this easier, I’ve curated handwritten placement notes that simplify revision and help you prepare smarter.
Why Placement Notes?
Placements are not just about solving coding problems – they test your fundamentals across CS subjects. Handwritten notes make revision faster, especially in the last few days before interviews. They cover concepts that recruiters repeatedly test in Aptitude, Coding Rounds, and Technical Interviews.
DSA & Algorithms (For Coding Rounds)
Data Structures & Algorithms form the core of coding interviews. These notes include:
- Sorting, Searching, Recursion, Greedy, and DP
- Arrays, Strings, Linked Lists, Trees, Graphs, Hashing
- Quick Time & Space Complexity review
👉 Perfect for last-minute brushing before coding tests
DBMS & SQL (Frequently Asked in Interviews)
Database concepts are a must for technical rounds. These notes help you with:
- Normalization, Keys, Indexing, Transactions
- SQL queries (joins, subqueries, aggregate functions)
- ACID properties & relational algebra basics
👉 Many interviewers ask candidates to write SQL queries on the spot – these notes give you patterns to remember.
Operating Systems & System Design
Every CS student must know OS concepts. These notes cover:
- Scheduling, Deadlocks, Synchronization, Memory Management
- Paging, Segmentation, Threads
- Basics of System Design – scalability, caching, load balancing
👉 Crucial for both service and product-based interviews.
Operating Systems Handwritten notes
System Design Handwritten notes
Web Development (HTML, JavaScript, Node.js)
For full-stack and backend roles, web fundamentals are essential. Notes include:
👉 Useful for SDE roles involving backend & web.
Java, C++ & OOP Concepts
Coding rounds often let you choose your language. These notes provide:
- Syntax recap for Java & C++
- OOP principles: Encapsulation, Inheritance, Polymorphism, Abstraction
👉 Interviewers love testing your OOP understanding with examples.
Cloud, Machine Learning & Data Science Basics
Not always mandatory, but companies increasingly ask about Cloud & AI basics. Notes cover:
- Cloud computing
- Intro to ML algorithms (Regression, Decision Trees, Clustering)
- Data Science pipeline: cleaning, feature engineering, model building
👉 Great add-on for AI/ML, Data, or Cloud-focused roles.
Why These Notes?
- Handwritten & concise → Easier to revise than bulky PDFs
- Placement-focused → Covers frequently asked concepts
- All-in-one → Saves time juggling between multiple resources
