The Ontology and Engineering Philosophy -- How Palantir Thinks About Software

This module dives deep into the Palantir Ontology -- the semantic data layer that is Palantir's true technical differentiator -- and the engineering philosophy it embodies. Candidates will learn about ontology-oriented software development, the OSDK, open-source contributions, and the technical stack. For engineering candidates, understanding this philosophy is essential for system design interviews and for articulating why Palantir's approach to software is fundamentally different.
