Not sure how the recruiter got my name, but received an email. Set up a ~45 minute behavioral phone interview, which led to a fairly straitforward 1 hour 15 minute online coding challenge. That led to an onsite interview, which was three technical interviews in the morning, a presentation called Palantir 101, and then a tour of the facility. It was a little odd - one of the other people interviewing was told to leave after the presentation, while the rest of us got the tour, and then were told to leave.

Had a chat with HR and then a technical interview with an engineer. They gave some some quite normal leatcode type questions that I had to answer to continue to the next steps.
