It was an on-campus interview with three rounds.

The first two were coding-related questions, while the third was HR + Technical.

• Round 1: I was asked array-related questions and SQL questions.
• Round 2: Java core concepts, binary tree questions, and a dynamic programming question on DFS.
• Round 3: "Why Oracle?" A question on operating systems. A question on linked lists, asking me to optimize it. I provided three variations.

Questions were based on DSA, which mostly focused on arrays, trees, and linked lists. I was also asked about Java core concepts and OS.
