Process, Questions & AI Prep Tips
Palantir's interview process uniquely combines algorithmic coding with a "decomposition" round where you break down a vague problem into concrete components. They test structured thinking.
Initial call to discuss your background and interest in Palantir's mission of building software for the world's most important institutions.
A timed coding assessment with 2-3 algorithm problems.
A live coding session with challenging algorithm problems, typically graph or dynamic programming focused.
Palantir's signature round: given an ambiguous, real-world problem, break it into concrete components, define requirements, and design a technical solution.
Discussion about your ability to work with high-stakes clients, handle ambiguity, and align with Palantir's mission.
Decompose: How would you build a system to detect supply chain disruptions?
Implement an efficient graph traversal for fraud detection networks.
Design a system that aggregates data from multiple government databases.
Tell me about a time you worked on a project with ambiguous requirements.
Implement an algorithm to find the shortest path in a weighted graph.
Decompose: Build a system to optimize hospital resource allocation during a pandemic.
How would you design a secure data integration platform?
Describe a time you had to communicate technical concepts to non-technical stakeholders.
Design an anomaly detection system for large-scale data.
Decompose: Create a logistics optimization system for disaster relief.
Practice the decomposition format: take a vague problem, ask clarifying questions, define requirements, then design.
Palantir values structured thinking — show your framework for breaking down complex problems.
Graph algorithms are heavily tested — study BFS, DFS, shortest path, and connected components.
Understand Palantir's products (Gotham, Foundry) and mission — they want engineers who care about impactful work.
Be prepared to discuss working with sensitive data and high-stakes clients.
The decomposition round is unique to Palantir — practice by taking vague product ideas and creating technical specs.
