I had three different rounds of interviews. Got bounced after the third one. The first round is just an HR interview. Just to make sure that you can speak ok with other humans. You get asked about your background and why you want to work at Palantir - EVERYONE asks you why you want to work at Palantir. There is one very easy 'technical' question you get asked. The second round was an (easy) software engineering interview. You go to coderpad and code up some solutions to some math algorithms. Think number of primes between 1 and n. There was also a 'if you had infinite resources, what data science problem would you want to work on and how would you approach it?' Kind of a very broad case study. The third round was similar to the second round. No coding but I did get asked some probability questions. Expected winnings of coin flips kind of thing. Also another case study question: you are in charge of digital subscriptions for the New York Times. How would you help improve revenue? Very broad but segues into some modelling questions. I didn't really enjoy the interview process. This could be sour grapes of course but I found the people I was interacting with fairly cold and brusque. There was absolutely no personal connection or friendly vibe in any of the technical interviews. The HR person being the exception. It just felt like the people who were interviewing me did not really have time for me and were not particularly interested in what I had to say. Also, no detailed feedback. Just a form rejection email when I didn't move on. I emailed to ask for real feedback but was told that they don't do that. I went through three interviews with your company. I feel like you owe me some real feedback. Even to say I'm not skilled enough in these areas. I found that unprofessional.
