Tips

Revise one programming language thoroughly, especially Java fundamentals, OOP, exception handling, collections, and strings. Practice arrays, strings, sorting, searching, and basic data structures. Prepare SQL queries involving joins, GROUP BY, aggregate functions, and subqueries. Be ready to explain your academic projects, your individual contribution, and the challenges you solved. Practice aptitude and verbal reasoning if they are part of your assessment.
