This was part of Oracle's campus recruitment process.

The process spanned two days on-campus, preceded by an online round that tested puzzle-solving ability and math skills.

The on-campus portion had four phases:

1. The first was a coding challenge, a simple program to test basic C++ proficiency.
2. Then, shortlisted candidates proceeded to a preliminary interview to test simple puzzle-solving.
3. The second interview focused on puzzles and problems designed to assess understanding and quick thinking.
4. The third round checked the ability to work in groups.
5. The final round was simply to announce selection.
