Frequently Asked Questions
They favor practical problem decomposition and data modeling over pure algorithm puzzles, with coding, a decomposition/design round, and behavioral questions.
An FDE works directly with customers to build and deploy solutions. Interviews emphasize decomposition, integration, and stakeholder communication.
High difficulty, but weighted toward practical modeling and decomposition rather than the hardest competitive-programming problems.
Practice decomposing open-ended problems, modeling data, and handling messy real-world inputs, plus clear stakeholder communication.
Palantir interviews are usually conducted over video or a shared coding platform. A desktop tool like GhOst runs outside the browser and stays invisible to screen share and proctoring, so it can provide real-time coding, system design, and behavioral help.
