J'ai postulé en ligne. J'ai passé un entretien chez Palantir Technologies (Palo Alto, CA) en janv. 2015
Entretien
Recruiter was very nice. Company is overall very energetic.
I had one recruiter phone screen and one phone technical interview. Then onsite interview of 5 rounds. Questions were pretty straightforward, I solved them quickly. But they told me after 2 days that I didn't do well enough in the coding and algorithms.
Some of the interviewers are very friendly, but some looks very tired and was not very responsive in talking.
They want to make sure that you want to join them badly, even though it's kinda hard to understand exactly why their products are important for their customers.
During the interview, I asked explicitly and they confirmed that people at Palantir works harder than other Silicon Valley company but the salary is not proportionally increased, because they love the work.
I guess they'll hire you only if you can really appreciate their products and culture and are fanatically passionate about the company.
Questions d'entretien [1]
Question 1
Phone interview:
Same with what others have mentioned here. Find duplicates, find duplicates within distance k, find fuzzy duplicates within distance k.
Onsite interview:
Running median, some follow-up of not using heaps and constant space
Min Stack
Find top k numbers in max heap
Design UI for a file explorer on a webpage
Design a Twitter API, no technical details, just discuss about it, performance, scalability, etc
Real coding on a laptop, not hard, don't worry about it.

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.

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.
