I applied online. The process took 2 weeks. I interviewed at Palantir Technologies (San Jose, CA) in Sep 2022
Interview
Just completed my Karat coding/technical interview. Interviewer was very down-to-earth and approachable, which helped reduce my nervousness. Interview was scheduled for 60 minutes - 15 minutes on intros, technical background, and 3 trivia questions. Remaining 45 minutes was allotted for 3 coding problems. What is really unique about Palantir's process is that we can request a "do-over" within 24 hours of the Karat interview if we felt we didn't do well.

Question 1
