What this interview will probe

Build the lowest layers of the stack underpinning Palantir Foundry and Gotham, working on distributed systems, database technologies, and large-scale data processing using Java and Go alongside open-source systems like Cassandra, Spark, and Elasticsearch. You'd ship performant, secure, scalable building blocks that the entire product platform depends on, deployed to demanding public- and private-sector institutions. A technical interview would probe data structures and algorithms, distributed-systems fundamentals such as consistency, partitioning, and fault tolerance, and your ability to design and debug a high-throughput storage or compute system.
