I applied online. The process took 3 weeks. I interviewed at Palantir Technologies
Interview
I applied online and was sent an online assessment that consisted of three problems each problem was building upon the previous. The problems were tree/graph related. I solved all three problems and passed the test cases.
After that, I was asked to do a Karat interview round. I did this round and it was a very positive experience. The interviewer was very professional. I had 5 minutes of intros. 10 minutes for three short questions basically time complexity and debugging code. After that, it was 45 minutes of coding problems. He told me that he will keep giving me problems until time runs out. I was able to completely code and implement two problems and I explained the idea and wrote some of the code for the third problem as well before we ran out of time. The questions were maze/grid/BFS type of questions.
After the Karat interview, I finally got to talk to a real person - the recruiter. During this 20-30 minute talk, we went over my resume and some basic questions and she told me that she will forward my resume to the hiring managers and will let me know if there is a role that is a good fit for me. If there is we will move to onsite. I was surprised by this because I had already invested few hours in their interview process just to find out that there may or may not be a good fit for me. After a week she contacted me to let me know there is no good fit for me at the moment.
It is frustrating that they make you go through all those interviews only at the end to tell you they do not have a good fit for you.
They try to sell the whole thing as "being very deliberate about their hiring process" which is an excuse for waisting your time.
I interviewed at Palantir Technologies (Miami, FL) in Jun 2026
Interview
Started with a recruiter screen where the whole point is just checking if you actually care about their mission and the real-world impact of their software, rather than just wanting a cool tech job. After that was a 90 minute hackerrank OA that felt more like an implementation mini-project with SQL and Python instead of abstract algorithms.
The onsite was a 4-round loop chosen from decomp, re-engineering, learning, coding, and sys design. Decomp is the most important one - they give you a super vague prompt like designing a chess game or tracking a disease from scratch, and you have to map out the inputs and logic out loud. Re-engineering gives you around 1000 lines of code with a very subtle logical bug to fix, and the learning round drops you into a random API with barely any documentation to see how fast you pick it up lol. Coding was standard LC mediums but they squeeze a 20-minute behavioral chat right into the middle of it, and sys design was heavy on data governance and fault tolerance. The final chat with the hiring manager is pretty intense too ngl. They will actually make you redo parts of the onsite you struggled with. For prep, don't just mindlessly grind LeetCode. Practice reading other people's code fast and structuring ambiguous problems. I got a really good Palantir coach on Prepfully who helped a lot to catch my blind spots and get a reality check before the actual loop. Overall, not very easy though

Question 1
A payment processing module has a race condition that produces incorrect totals under concurrent writes. Walk through how you would identify the root cause and propose a fix.
I applied through a recruiter. I interviewed at Palantir Technologies (Palo Alto, CA) in Jun 2026
Interview
Standard interview similar to their new grad. Recruiter, two technicals decomp and learning, and then hiring manager half behavioral half technical leetcode style. Really focused on why palantir, mission alignment, and role alignment.
I interviewed at Palantir Technologies (New York, NY)
Interview
Great interview process - 1. Recruiter call 2. Leetcode style technical 3. Scoping style (decomp) interview 4. Frontend coding 5. Another scoping (decomp round).
Interviewers were fun and engaging, and I felt challenged in a positive way.
