Palantir Technologies interview questions

I applied online, and within 3 weeks received an e-mail from a general HR rep. asking when I would be available for a call to discuss the position. We arranged a time 1 week later. During the call, I was first informed about the position; this outlined the job description given on the website, and also provided new information. I was then asked to cover my professional experience, technical experience, and if I had any questions of my own. The last question I had was about next steps. Evidently, there were 4 stages in the hiring process. First was this screening call. Happily, I didn't have to wait to learn if I moved on to the second stage. I was told that shortly after the call I would receive an e-mail containing instructions to complete a project. The goal of the project was to assess my analytical and creative skills. The call then ended, our conversation lasting about half an hour. For the project, they claim it will take 2-3 hours to complete, and it is to be done within 5 days of receiving the e-mail. (I recommend giving yourself plenty time, and begin immediately. Palantir's software is built for places like the CIA or JP Morgan, not your personal computer. I experienced a lot of lag, and I believe it was because it was demanding on my desktop.) It consists of 2 tasks: navigate their software to answer questions, and then come up with your own question and use the software to explore for insights; then you are to put your work into a PowerPoint, and e-mail it in. There's no way to prepare for this. It's sink or swim. It's not like the software is available to practice with ahead of time. You have to be very intuitive, and again, creative. Within 2 hours of handing my work back to the general HR rep., I heard from a new recruiter, requesting a time for me to chat on the phone with someone from team itself - third stage. Within a week, I had this interview; another half an hour conversation. As with before, I was given an outline of the work they do, and what specifically the role I was interviewing for entailed. Then I was asked why I was interested in the team, what my strengths were, what other ways I would use the software, as in, like how I used it for my project, and if I had any questions. A week later I heard from the initial HR rep., saying the team decided to continue with other candidates with stronger technical backgrounds. Palantir takes only the best of the best of the best. Making it so far into the process means a lot. Clearly at that stage anyone is more than capable of doing the job, it's just a matter of what the team needs at that time. I mention this because it is stressed in the job posting that technical skills are not only not required, but are not expected - so long as you're willing to learn. In this case, evidently they needed more expertise in that area. Put another way, it wasn't a fit for me yet. The fourth and final stage would have been an in-person interview with the team.

Can't remember first interview, standard coding tests. Secondary interview was in office, with four people. Various questions asked, usually coding/algorithms. Pretty basic things, know the runtime of your algorithms, make sure everything is in smallest big O possible. Sample questions were: correct a series of code, Find the largest algorithmic progression Regular palindrome shenanigans Some coding question that was effectively "Merge Two Sorted lists"
