I talked with a recruiter and was immediately invited on-site.

I was recommended by a friend who is an Oracle employee, so perhaps that helped me bypass the initial screening process.

The interviews with the team were mostly laid-back.

There was a coding problem on a computer with an editor and the ability to look up details online while programming. Afterward, they asked about the time and space complexity of my solution.

Additionally, there was a whiteboard coding interview and a few behavioral questions (e.g., "Tell me about a time when...").

A second phase would have involved bringing a coding sample to discuss and giving a whiteboard technical talk, but I decided not to proceed with Round 2.

The questions were similar to those in Cracking the Coding Interview or one of the other popular books.

Definitely worth studying if you are rusty on your undergraduate-level algorithm design.
