Computer Science Subjects Interview Questions
Apart from coding questions, top tech companies like Amazon, Microsoft and Flipkart also asks question from core computer science subjects. Majorly question are asked from subjects like Object-Oriented Programming, Operating System (OS), Database Management System (DBMS) and Computer Networks. Knowledge of these subjects is essential for solving real-world problems and system design.
This article contains a list of the most frequently asked questions from Object-Oriented Programming, Operating Systems, Computer Networks, and DBMS in the interviews of the top product-based companies like Amazon, Microsoft, Flipkart, Paytm etc.
Object-Oriented Programming Interview Questions
Object-Oriented Programming (OOPs) is a way of writing code by organizing it into objects that represent real-world things. It is important in interviews because it helps create clear, reusable, and easy-to-manage code. Important topics in Object-Oriented Programming are Inheritance, Polymorphism, Abstraction and Encapsulation.
Operating System Interview Questions
Operating System (OS) concepts are important for system design and low-level programming because they help manage hardware and run programs efficiently. These topics are often asked in technical interviews. Key concepts to focus are Processes & Threads, Scheduling, Deadlocks, Memory Management and Virtual Memory.
Database Management System Interview Questions
Database Management Systems (DBMS) are essential for backend development and efficient data handling. They help store, organize, and retrieve data quickly, making them a key topic in technical interviews. In DBMS, most questions are asked from topics like Normalization, Indexing, Transactions (ACID properties), SQL or NoSQL databases and Joins.

Computer Networks Interview Questions
Computer Networks are important for distributed systems and cloud computing because they let devices connect and share data. Networking basics are often asked in interviews, especially for cloud and system roles. Important topics in Computer Networks are OSI model, TCP/IP, HTTP vs HTTPS, DNS and Load Balancing.
Software Engineering Interview Questions
Software Engineering is important in interviews because it shows how you plan, build, and maintain software projects effectively. Employers want to see that you understand how to deliver quality software in real-world teams. Key topics of Software Engineering include SDLC models, System Design Basics, Testing & Debugging and Version Control.
Conclusion
Preparing for interviews at top companies like Amazon, Microsoft, and Flipkart requires a solid grasp of fundamental computer science subjects such as Object-Oriented Programming, Operating Systems, DBMS, and Computer Networks. These top computer science interview questions in given domains often test both theoretical knowledge and practical problem-solving skills. By focusing on frequently asked topics, practicing SQL queries, and understanding core networking protocols, you'll build the confidence needed to excel in technical interviews. Additionally, leveraging comprehensive resources, such as video courses and structured interview guides, can further enhance your preparation, helping you tackle even the most challenging interview questions.
