Typical interview loop

How Palantir Technologies usually runs it for applied AI and LLM engineer roles.

  1. Recruiter call

    Focus: Motivation & culture fit

    A short call about why Palantir, what you liked and disliked in past projects and where you want to go; culture fit is a real filter here.

  2. Phone interview(s)

    Focus: Coding, thinking out loud

    One or two 20-45 minute technical phone interviews, typically an algorithms problem framed around building something for an end user.

  3. Onsite: decomposition

    Focus: Structuring open-ended problems

    You break a vague, real-world customer problem into inputs, data model, logic and outputs and propose a pragmatic solution, with little or no code.

  4. Onsite: coding & re-engineering

    Focus: Working code, debugging existing systems

    Practical coding with an end-user framing, and/or finding and fixing bugs in a larger unfamiliar codebase; each onsite round also carries some behavioral questions.

  5. Onsite: learning or system design

    Focus: Learning speed or architecture

    Depending on track, either ramping up on an unfamiliar concept or API during the session, or a design round on data-heavy systems.

  6. Hiring manager interview

    Focus: Resolving doubts, ownership, mission

    A final hour that often revisits an area where the onsite panel had doubts, plus motivation and mission fit.
