Prepare well for basic programming concepts especially OOP and DBMS
An advice tip converted into a question format for preparation. It covers fundamental computer science concepts essential for software roles.
Why Interviewers Ask This
OOP and DBMS are foundational for almost all software development roles. Interviewers ask related questions to ensure you have a strong theoretical base before diving into complex coding problems. These concepts are critical for writing maintainable and efficient code.
How to Answer This Question
Review the four pillars of OOP: Encapsulation, Abstraction, Inheritance, and Polymorphism. Understand relational database concepts like normalization, indexing, and ACID properties. Be ready to write code snippets demonstrating these concepts.
Key Points to Cover
- OOP pillars
- Database normalization
- ACID properties
- Code reusability
Sample Answer
Basic programming concepts like OOP and DBMS are crucial. For OOP, I focus on encapsulation to hide internal state and inheritance to promote code reuse. In DBMS, I ensure I understand normalization to reduce redundancy…
Common Mistakes to Avoid
- Knowing theory but failing to apply it in code
- Confusing normalization forms
- Ignoring the relationship between OOP and databases
