Applied through an acquaintance who already worked there. I spent a lot of time researching the company and seeing if I was good fit. Speaking with folks who worked there was awesome - they were friendly, smart, motivated and enjoyed talking about their company. From the outside looking in, it seemed like a great place to work - where you feel good about what you do and that you can make a difference. The interview process was well organized. Once my application was submitted it took a week for the first round interview. The first round interviewer asked normal questions trying to assess fit and desire to work at Palantir. The second round interview was more structured problem solving and how one would approach specific problems. The questions were thoughtful and the interviewer was thorough. I did not make it to the next round. Seems like a great company though - you should apply.
