It was a friendly process. Since I am from Mechanical, they didn't ask me hardcore CS concepts. They asked about projects. Then about my internship. They asked simple algorithms. They asked two puzzles also. It was not that difficult, but they probably expect better-optimised algorithms. They asked me questions like reversing an array. They also asked about finding duplicates in an array and deleting them.

the interviewer was quite polite and helpful. he was patient and asked me where im from, why do i want to join oracle and patiently waited for me complete my coding qs on the piece of paper
