I applied online. The process took 2 weeks. I interviewed at Palantir Technologies in Nov 2022
Interview
Technical 1 hour interview via Karat. The interviewer briefly introduced himself and explained the process. I had 60 seconds to tell about my background. Then we had 10 minutes for the first part (3 questions about time complexity), and 40 minutes for the second part (2 coding questions, I didn't have time for the 3d one, though I gave some thoughts; they were all pretty about the same thing). In the second part I was asked about time and space complexities as well. The questions were really easy.

Question 1
Why choose Palantir, what about tech interests you, how do you use AI in daily life, etc.
Just the pre-screen behavioral round, was asked: why are you choosing to get your master's degree, what classes do you enjoy, what are you looking for in an internship? Seemed like just a deep dive on my interests, didn't even ask why palantir.
