FAQ

Why does Palantir reject a candidate who mentions O(1) lookups but no memory cap?
Because the FAIR rubric penalizes missing Robustness evidence; Palantir requires explicit memory limits, as shown by Lina’s 120 MB profile.

What concrete metric convinces Palantir’s hiring committee that a GraphQL solution is acceptable?
A latency under the 150 ms SLA on the Graphite dashboard, accompanied by a memory‑usage report below 256 MB, as demonstrated by Maya’s failed attempt when she gave no numbers.

Can I succeed with a pure design discussion without coding a prototype?
No. Palantir’s debriefs consistently score Functional and Accurate only when a working prototype is presented, as in Dan’s mock where the candidate shipped a cleanup step inside the code.
