0th round: Phone screen with a recruiter. Pretty straightforward and friendly. Questions about my interests, where I was in my job search, why I wanted to leave my current job. It took several weeks on their end to schedule it. 1st round: One Skype interview with a deployment strategist. For scheduling reasons I had to take it as a phone call and that was acceptable to them. 3 strengths, 3 weaknesses, specific examples of each. 2nd round: Casual lunch plus two in-person interviews, all with tenured deployment strategists. One interview was a video conference with someone from another office. One interviewer was very obviously texting under the table while I answered questions. Each interview had a fit portion with questions about my interest in Palantir, motivations, past experience, and why I was leaving my current employer. Each interview also had a couple case-types of questions and one interviewer gave me a brain teaser. (this is as far as I made it) 3rd round: Interview with someone pretty senior, format supposed to be similar to 2nd round Several friends told me about an unexpected 4th round interview with an individual (deployment strategist or engineer) from the specific team interested in them
