Palantir Karat Interview: Format, Questions & Prep (2026)
LeapFork is an independent interview preparation platform, not affiliated with Palantir or Karat, Inc. This guide is based on candidate-reported experiences and publicly available information.
Palantir Technologies — builder of the GOTHAM, FOUNDRY, and AIP platforms — uses Karat for first-round technical screening of software engineering candidates. Palantir is known for a rigorous, multi-stage interview process; the Karat screen is the initial technical filter before company-specific rounds.
LeapFork is an independent prep platform. This guide is based on candidate-reported experiences. Palantir has a reputation for high hiring bars, but the Karat screen specifically is calibrated to the same LeetCode easy-to-medium range as other Karat client companies. The company-specific rigor appears in later rounds, not in the Karat format itself.
How Palantir Uses Karat
The Palantir Karat screen follows the standard 60-minute format: introduction, domain questions, and approximately 40 minutes of live coding. Domain questions at Palantir may lean toward software engineering fundamentals — how you approach system problems, trade-offs between data structures, or your debugging process.
The coding problem follows Karat's standard three-part progressive structure. Palantir does not appear to customize the Karat problem set. What varies is what follows the Karat screen: Palantir's subsequent rounds are known to be more technically demanding and involve working on problems relevant to Palantir's product domain (data pipelines, graph structures, operational analytics). The Karat screen is a prerequisite, not a guarantee of difficulty reduction.
Role Levels & What to Expect by Level
Palantir uses Karat for software engineering roles across multiple tracks, including the Forward Deployed Software Engineer (FDSE) role, which is a distinctive Palantir-specific position combining engineering with client consulting. Standard SWE roles also use Karat for initial screening.
Role levels vary, but Karat appears most commonly for entry-level through senior SWE positions. Palantir's compensation and leveling structure differs from standard FAANG leveling — your recruiter is the best source for how your specific role maps to the interview process.
Question Patterns to Practice
Based on candidate reports, Palantir Karat problems follow standard Karat difficulty: LeetCode easy-to-medium, algorithmic rather than system-design focused.
Patterns to prioritize:- Hash map state tracking: The dominant pattern. Frequency maps, complement lookups, first-seen-last-seen tracking.
- Graph-adjacent patterns: Given Palantir's product focus on data relationships, domain questions may reference graph or network concepts. The coding problem itself is standard Karat, but being able to discuss graph fundamentals (BFS, DFS, adjacency lists) is valuable for domain questions.
- String parsing: Parsing structured data, validating formats, or reformatting output.
- Matrix traversal: BFS/DFS on 2D grids.
LeapFork's timed simulation mirrors the actual Karat format: live coding, AI-graded performance, and a speaking AI interviewer. Free to start.
Run a Free Simulation →2-Week Prep Plan
Week 1: Core algorithm patternsDays 1–3: Hash map intensive. Solve 3–4 problems daily in the frequency/complement/state-tracking category. Measure both correctness and time per problem.
Days 4–5: Graph fundamentals. Write BFS and DFS from memory on a whiteboard or blank file. Solve 2 connected-components problems.
Days 6–7: String and matrix problems. Speed is the goal — these patterns should be auto-pilot by now.
Week 2: Pressure and communicationDays 8–10: Full 40-minute timed sessions. No extensions. Review what part you were on when the clock hit 40.
Days 11–12: Domain question practice. For each of these topics, give a 2-minute verbal explanation: hash tables vs. balanced BSTs, BFS vs. DFS, when to use a heap. Practice out loud.
Days 13–14: Two full timed simulations with camera. Debrief after each.
Frequently Asked Questions
The Karat screen itself is calibrated to the same difficulty range regardless of the client company. What differs is what follows: Palantir's subsequent rounds are known to be more demanding. Pass the Karat screen with the same preparation you would use for any Karat interview.
The FDSE role at Palantir combines software engineering with client-facing deployment work — FDSEs work closely with enterprise and government clients to deploy and customize Palantir's platforms. The Karat screen is used for this role as an initial technical filter. FDSEs need strong coding skills as well as communication ability, which the Karat rubric measures.
Palantir's process after the Karat screen typically includes additional technical rounds with Palantir engineers, often including a take-home or extended technical exercise, followed by a decomposition and culture interviews. The full process varies by role and team.
