OA -> Karat -> Behavioural -> Onsite (Learning + Decomposition) -> Hiring Manager (45 min Behavioural + 15 min Decomposition) -> Offer Each step of the interview process you feel like the recruiter is there to help you. They would arrange a quick chat to give you feedback after each stage, and give advice to prepare for the next. The feedback they conveyed both from their perspective and the rest of the interviewers was the most insightful feedback I got in any interview process I went through. Every company likes to say they want to understand how you think, and don't care about you getting the problem 100% right the first try. Palantir is one of the few companies where I actually think that is the case. The OA and Karat interview focus on the fundamentals which is closer to LeetCode, but after that the interview process is unique to Palantir. The behavioural interviews are actually quite difficult as the company has a strong idea who they consider a fit. I've heard lots of people fail at this stage. My advice would be to be blunt and honest to yourself, as they can see right through your bs. Learned that the hard way the first time I applied. After that comes the Onsite. Both decomposition and learning last 45 min and start with a 15 min behavioural portion. Decomposition is similar to a System Design interview, however it takes much higher focus on exactly that, decomposition, rather than nailing in the implementation details. The learning interview is something you can't prepare for as you're given a new concept they think you haven't encountered before, and are given problems where you're supposed to demonstrate how you learned from the documentation / examples you were provided. The hiring manager interview is last. Here you repeat the type of interview you performed worse on during the onsite (for me that was decomp) where they try to make sure you won't repeat the same mistakes. The HM makes a lot of effort to really understand what interests and drives you. I can't stress enough how important it was to communicate with your interviewer. Especially with these kinds of interviews it was critical to ask the right questions and explain the reasoning behind your decisions, rather than spit out the right algorithm. I can honestly say I very much enjoyed speaking to each person during the interview process. I really felt like they were truly interested in what I had to say and who I was. After each interview I was given feedback almost instantly. After the onsite within 3 hours. After HM I got the offer the next day.
