Interview consisted of a 45 minute technical phone call on algorithms. There was no coding part in the first round. Palantir is known to be hard so I sort of went into the process a nervous wreck.

Question 1
What is the time complexity to find the median in an array?
I interviewed at Palantir Technologies (Washington, DC)
Interview
20-minute Phone Screen (background and interests) -> Coding Assessment (3 questions: 2 LC medium and a REST API task) -> 45-minute Technical Interview -> Virtual Onsite (Learning and Decomp) -> Final Round with Hiring Manager
The process included two phone screens, two technical rounds (one DSA and one learning decomposition), and a hiring manager interview. They had my email wrong, so I kept getting notified only a day before interviews, which really sucked.

The interview process was straightforward and well-organized. I first had a short screening call, followed by a virtual technical interview with the hiring team. Everyone I spoke with was professional and clear about expectations, which helped the process feel smooth and comfortable.
