Be thorough with your resume, ensuring clarity and relevance. Revise basic sorting algorithms (Bubble, Selection, Insertion), C++ concepts (pointers, OOPs, STL), SQL queries (JOINs, subqueries, indexing), DBMS fundamentals (normalization, transactions, ACID properties), ER diagrams (entities, relationships, attributes), leap year logic (divisibility by 4, 100, 400), and the differences between RDBMS and DBMS (structured vs. unstructured, normalization support, constraints). Focus on problem-solving, coding efficiency, and database optimization. Practice coding on platforms like LeetCode and GeeksforGeeks, and review common interview questions for technical rounds. Prepare confidently for a strong impression.
