I originally applied for a software engineering position to which I was rejected without interview. Two months later the recruiter reached out saying that I'm better suited for the FDE role and that she'd like to schedule a phone interview. The code pair exercise was pretty easy and I enjoyed the conversation with the FDE that I spoke to. Four hours later I was invited for an onsite the following week. The first interview onsite was actually through skype with someone in DC and it was another code pair that I thought went well. The second interview was more of a systems design type of question that I definitely could have performed better in. The third interview was the one that left a little bit of a bad taste in my mouth. The interviewer asked a very open ended question after glancing over my resume (he didn't know what he was going to ask prior to entering the room), and I attempted to identify constraints and whatnot but he wasn't terribly helpful. I understand the point of this type of question, which is to see how you answer a completely new problem, but I still think that my interviewer had a specific way that he thought that the problem should be solved without really engaging in much of a conversation as I attempted to solve it. After the three interviews I had a casual lunch with another FDE where I was able to ask any remaining questions. Overall i thought that the process and questions were very fair except for the one above instance I already mentioned. They care a lot about passion and drive to solve complicated problems and Palantir seems to be filled with the type of driven people that I someday hope to work with. However, I would have appreciated a little more feedback than the usual you're not a good fit/other more qualified candidates given that I took a vacation day to go to the interview. When I interviewed at Google I received very detailed feedback that was helpful in my future interviews.

You first do a coding challenge with an engineer and if that goes well you do the full round. The full round is two interviews. One is a system design interview and then a second is the learning interview.
