Palantir's interview process has two main parts: one or two phone interviews, then an on-site round with more of the team. Palantir says the number and format of interviews is personalised to your skillset and the type of role you want, so two candidates can have different processes.
Everything below comes from Palantir's own careers pages and its company blog, linked as we go. Where Palantir doesn't say something, we say so.

What is the Palantir interview process?
Everyone starts with one or two phone interviews, and if Palantir thinks there's a fit, it invites you to an on-site round. Palantir says the interview process for engineers varies with the role you apply for, Software Engineer or Forward Deployed Software Engineer, and that it provides prep material ahead of each step.
Palantir's blog post on interviewing at Palantir (September 2020) says it doesn't have a single "perfect fit" in mind when it interviews. It says it tries to understand candidates holistically, welcomes non-traditional backgrounds and looks at your potential for growth as well as your current skills.

What is the Palantir hiring process?
You apply to an open role, interview by phone, then interview on site, and Palantir decides whether to make an offer. A few details from its careers pages:
- Early talent eligibility. Palantir's new grad and early talent roles are open to people graduating in Fall 2026 or Spring 2027, or with less than six months of industry experience.
- Two engineering tracks. Software Engineers sit in Product Development ("one capability, many customers"). Forward Deployed Software Engineers sit in Business Development and work towards outcomes for specific customers ("one customer, many capabilities").
- Team placement. For new grads, Palantir says placement depends on what it learns in interviews (your experience, interests and motivations) and on what the business needs.
- Visas. Palantir says it is supportive of visas and has a Mobility Team to help.
Palantir doesn't publish how long the whole process takes. Treat the timelines on prep sites as unconfirmed, and ask your recruiter.
What happens in the Palantir phone interview?
Palantir's phone interview guide says the process begins with one or two phone interviews, typically lasting 20 to 45 minutes each. You should be ready to talk about your background, your experience and why you're interested in Palantir.
If you're applying for an engineering role, you'll also get a technical question on your coding. Palantir says it expects every engineer, whatever their speciality, to be able to work through a coding question. It may ask you to use HackerRank or Google Docs, so check your internet connection beforehand. Our guide to HackerRank tests explains how that platform works.
Palantir's own tips for the call:
- Find somewhere quiet and make sure your phone works. Palantir suggests a headset so you can talk while typing.
- Think out loud. On the phone, talking is the only way the interviewer can follow your reasoning.
- Ask questions if anything about the problem is unclear.
- Start simple and then expand. Think about the high-level design first, then get a simple solution working before improving it.
- Have a pen and paper ready to sketch your thinking.
At the end, the interviewer will ask if you have questions. Palantir says candidates often ask what Palantir does, what the interviewer works on, what it's like to be new and how the internship programme works. Afterwards, Palantir says it typically gets back to you within a week or two at the latest, either for another phone interview or to invite you on site.
What happens in the Palantir on-site interview?
If the phone interviews go well, you meet more of the team in an on-site round, either in person or virtually. Palantir's getting hired page says it will ask how you've executed, challenged yourself, motivated others and made judgements, and where you've failed in the past. It says it looks for people who are "bright, adaptable, and eager to be part of a tight-knit team".
Its advice for the on-site:
- Be yourself. Palantir says culture fit matters to it on both sides.
- Think about your biggest professional or academic accomplishments, and your failures.
- Tell them what you're passionate about. Palantir says there's no wrong answer.
- Ask clarifying questions on analytical and technical problems, and talk through your approach. Palantir works in close, collaborative teams and wants to see you engage with the interviewer.
If you travel for an in-person interview, Palantir says it coordinates the trip. It also says you can wear whatever you're comfortable in.
What engineering interviews assess
Palantir publishes guides to the five engineering competencies it values most:
| Competency | What Palantir says it means | Palantir's preparation advice |
|---|---|---|
| Writing good code | Code that is efficient, free of bugs, easy to test, and easy to read and maintain | Write code. Plan the translation from algorithm to code, think about edge cases and testing, and keep naming and structure tidy |
| Analysing the efficiency of code | Making code run with optimal complexity and storing and moving data efficiently | Know O notation, remember space complexity, and think about real-world trade-offs |
| Navigating open-ended questions | Problems with many possible solutions, each with trade-offs | Build real things. In the interview, set out alternatives and trade-offs, then commit to a concrete approach |
| Solving technical problems | Using technology to solve hard problems that may not be technical themselves | Solve lots of problems and look for patterns. Try a special case or a simpler version first |
| Working inside existing systems | Fixing bugs and adding features in code and systems you didn't write | Read old code, swap projects with a friend, or fix a small bug in an open source project |
On languages, Palantir says it's fine with most imperative languages, including Java, Python, C/C++, C#, JavaScript, Rust, Go and TypeScript. It won't accept non-imperative languages such as Prolog, Lisp or Erlang, or very old ones such as Cobol and Fortran. It doesn't ask about obscure language features. Be ready to code on a whiteboard on site; Palantir can provide pen and paper or a computer on request.
Palantir's own pages don't give the open-ended round a name; they call the skill navigating open-ended questions. In Palantir's 2020 blog post, a Deployment Strategist describes the useful technique as deconstructing a problem and explaining step by step how you'd address it.
Does Palantir have an online assessment?
Palantir's careers pages don't describe a separate online assessment. The coding it documents happens inside the phone interview, sometimes on HackerRank or Google Docs, and in the on-site round. If you're sent a test link, follow the instructions in that email, and treat the question counts and formats on prep sites as unconfirmed.
What questions does Palantir ask in interviews?
Palantir doesn't publish a list of interview questions. The ones below are built from what its pages say it asks about and assesses. Use them to prepare, not as a script.
1. Tell me about your background and why you're interested in Palantir.
Palantir's phone interview opens here. Keep it to a couple of minutes, and make the "why" specific: a kind of customer problem, one of its platforms or the Dev versus Delta track you're applying for. A Palantir engineer in the 2020 blog post advises understanding the business you'd be joining.
2. What is your biggest professional or academic accomplishment?
Palantir tells candidates to prepare for this. Pick one where you made the decisions, explain what was hard, and say what changed because of your work.
3. Tell me about a time you failed.
A Palantir hiring manager wrote that it wants to hear about an actual failure and what you learned from it. She linked this to introspection: all Palantir roles are high-ownership, so you need to be critical of your own work. Choose a real failure and spend most of the answer on what you'd do differently.
4. Tell me about a time you motivated other people.
Palantir names motivating others as something it will ask about. Describe the situation, why people weren't motivated, what you did and the result. Peer influence counts as much as formal leadership.
5. Describe a judgement call you made without all the information.
Palantir asks how you've made judgements. Explain what you knew, what you didn't, the options you weighed and why you chose one. Saying what you'd check next shows the same thinking it wants in open-ended problems.
6. What are you passionate about?
Palantir says there's no wrong answer and that it wants to see you get fired up about something you love. Pick something genuine and talk about it in detail.
7. Solve this coding problem.
Expect at least one in the phone interview for engineering roles. Palantir's advice: think out loud, ask about anything unclear, get a simple solution working first, then improve it. Mention edge cases and how you'd test the code.
8. What's the complexity of your solution, and can you improve it?
This tests the efficiency competency. State time and space complexity, then talk about practical gains too. Palantir notes that an O(n) solution can still loop n or 2n times, and that extra data structures aren't always worth the space.
9. How would you build a system to solve this customer's problem?
This is the open-ended format. Ask questions to pin down what the user needs, set out two or three approaches with their trade-offs, then commit. Palantir's guide says to deliver a functioning idea first and expand it afterwards.
10. Here's some code you didn't write. How would you fix this bug or add this feature?
This tests working inside existing systems. Form a hypothesis about how the code is organised, test it, and resist rewriting everything. Palantir's guide warns against the urge to declare existing code bad.
11. Explain a technical concept you know well to someone non-technical.
Palantir says new grads need to communicate technical concepts effectively, and Forward Deployed Software Engineers work directly with customers. Pick a project from your CV and explain what it does and why it matters, without jargon.
12. Why Software Engineer rather than Forward Deployed Software Engineer (or the other way round)?
Show you understand Palantir's own distinction: one capability for many customers, or one customer with many capabilities. Link your choice to work you've enjoyed.
13. Do you have any questions for us?
Palantir says this is your chance to find out what interests you. Ask about the interviewer's current work, how new people are placed on teams or what a strong first few months look like.
How to prepare for a Palantir interview
- Read Palantir's five competency guides and practise against each one.
- Write code daily in one mainstream imperative language, talking through your reasoning out loud as you go.
- Practise on a whiteboard or paper, since you may not have an editor on site.
- Build or fix something real. Palantir suggests building an app that solves a problem in your life, or fixing a small bug in an open source project.
- Prepare four or five stories on accomplishments, a real failure, motivating others and a hard judgement call. Our STAR method guide shows how to structure them, and our list of behavioural interview questions gives you more to practise on.
- Learn what Palantir does for its customers, and decide which engineering track fits you.
- Do a mock interview with someone who will push back on your approach, so you practise talking a problem through with an interviewer.
Practising realistic work tasks
Palantir's interviews favour how you approach real problems over memorised answers. Cohesyve, which publishes this guide, runs practice job simulations for your role, with a scored report on where you lost marks. It isn't affiliated with Palantir and doesn't use Palantir's interviews or questions.
