Interview
I interviewed for a software engineering internship for the Fall of 2018.
Rounds:
Recruiter phone chat: Make sure you can answer why you want to work at Palantir in depth. Some people can get rejected at this round.
Coding challenge: Detecting Contractor Fraud. You do not need to pass all test cases to advance, I passed 17/22. Long question but not difficult in terms of algorithms. String parsing.
Technical phone screen: Behavioural and technical question related to implementing a custom comparator. Lots of discussion about trade offs of the code. Did not need to run code.
Onsite: Three interviews. Systems design, bug bash, technical algorithmic question. All open-ended questions, enjoyed the interview. My interviews were followed by a product demo then meeting with the hiring manager.
I ended up not getting the offer and I suspect it’s because I wasn’t enthusiastic enough about the Palantir mission during my hiring manager interview. Overall positive experience, got a good impression of Palantir and will re interview next year.
One thing I want to note about Palantir is that they are very flexible with you choosing the location, ie: NYC, Palo Alto, London which is great.

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.

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.

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.
