11.1What behavioral questions employers say they ask11 minProLive

You can list the behavioral topics your targets publish or candidates report, and map each to a story you have.

What it covers

What Palantir publishes
Company-wide and engineering-wide guidance
Values and mission
Culture and fit conversations
Career-history interviews
Be real, not rehearsed
Your story map

Key takeaways

Palantir says onsite interviewers ask how candidates executed, challenged themselves, motivated others, made judgments and failed.
Salesforce, Notion, Snowflake and Anduril publish that they ask behavioral questions, on pages not written for FDEs alone.
A Palantir hiring manager said they don’t necessarily want a prepared statement of what candidates think the company wants to hear.
Prepare each job on your résumé as your manager there would describe it.
Map every topic to a story before you write one; a row with no story is the next story to write.

11.2The stories to prepare11 minProLive

You have one drafted story for each of the eight story types, each naming a customer or user and a result.

What it covers

Why eight types
Ownership and stakeholder
Reversal and alignment
Deadline and failure
Pattern and saying no
Reusing one story for several questions

Key takeaways

Eight flexible stories let you answer a wide range of behavioral questions.
Every story names a person you served and what changed for them.
A failure story must include what you changed afterward.
Tag each story with the questions it can answer.

Practice

1 more planned.

Do this now

Write your eight story cards, then tell your failure story aloud with what you changed afterward

11.3STAR, adapted for customer work10 minProLive

You can tell a story with the customer’s situation, your decision, the trade-off you made and a measured result.

What it covers

Where plain STAR falls short
The customer’s situation
Your decision and the alternatives
The result, and who measured it
What you would do differently

Key takeaways

Spend the fewest words on the situation and the most on your decisions.
Name the alternative you rejected.
Say who measured the result.
Close with what you would change.

11.4Answering in about a minute, then the follow-ups9 minProLive

You can tell each story in about a minute, our target, and answer three follow-up questions on it without repeating yourself.

What it covers

Why short wins
Cutting the setup
Planning the follow-ups
Going deep when asked
Timing practice

Key takeaways

A short first answer invites the follow-ups where you show depth.
Candidates report interviewers probing past work in depth.
Prepare the three follow-ups you would ask yourself.
Time every rehearsal.

Practice

2 more planned.

Do this now

Time your deadline story to about a minute, then answer its three follow-ups without repeating yourself

11.5The ownership audit: from ‘we’ to what you did9 minProLive

You can rewrite a story so every decision has a clear owner, without erasing your team.

What it covers

What the audit checks
Collective and passive phrasing
Crediting the team fairly
Before and after
What the evidence does and does not say

Key takeaways

One prep guide claims FDE hiring managers screen for ‘I did’ over ‘we did’, and cites no source; none of the employer statements we collected mentions pronouns.
We teach the audit because a hiring leader says he asks candidates what they were responsible for.
Split each decision three ways, who proposed it, who decided and who carried it out, and name each by role.
Passive voice and a mid-sentence ‘we’ hide the owner; audit a transcript of your spoken answer, not just your draft.
End with what would have happened without you, and why nobody else would have stopped it.

Practice

2 more planned.

Do this now

Audit your ownership story, then answer ‘which decisions were yours alone?’ aloud

11.6‘Why this company’, built from what the company publishes11 minProLive

You can write a ‘why this company’ answer for each target that cites something the company published and connects it to your work.

What it covers

Generic answers and why they fail
Reading what the company publishes
Mission-first companies
Connecting their work to yours
The application essay

Key takeaways

Anthropic’s FDE application asks why you want to work there and says great answers are often a few hundred words.
Palantir says it looks for mission commitment in candidates’ backstories.
Quote the company’s own writing, then connect it to a decision you made.
Check the answer against the ways a second interviewer would ask it, using the same facts each time.
Update the answer the week of the interview.

Practice

1 more planned.

Do this now

Fill a company sheet for your first target, then answer the question aloud in about a minute

11.7Your first months: the interview answer and the real plan12 minProLive

You can answer ‘what would you do in your first months?’ with a plan that learns before it builds, and turn the same plan into your own first quarter with what you would measure.

What it covers

What the question is testing
Month one: learn the customer and the product
Month two: wire the slice in and measure it
Month three: a pattern back to the product
Onboarding programs employers describe
Mistakes leaders describe
Measuring yourself, and the weekly decision log

Key takeaways

Learn before you build, but put something small in a user’s hands within the first month.
One FDE leader names generalizing too early as his team’s biggest mistake.
Salesforce describes an onboarding program and pods; ask how yours works.
Plan to bring one pattern back to the product team, and say how you would measure your own first quarter.

Practice

1 more planned.

Do this now

Answer aloud: you are placed with a new customer next week; what does your first month look like?

11.8Public-sector and defense loops: clearance, mission and compliance11 minProLive

For a government or defense FDE role you can answer clearance and mission questions truthfully and exactly, explain how FedRAMP and impact levels limit a design, and decide early whether the mission is one you want.

What it covers

What employers ask on the application: clearance, travel, location
What candidates report: fast tracks for clearance holders
The mission conversation: why this work, said plainly
FedRAMP and impact levels in a design answer
On-site and classified work: what changes day to day
Deciding before you apply

Key takeaways

Palantir’s US Government FDSE application asks about clearance status and travel, and LangChain’s federal posting asks for architectures that meet FedRAMP and DoD impact levels.
Candidates holding clearances reported skipping early Palantir rounds, and one Palantir Government candidate attributed a rejection to mission alignment.
Say plainly why you want this mission, from something you did, and decide your line before the loop.
Decide before you apply whether you want the travel, the on-site work and the mission.

What behavioral questions employers say they ask

You can list the behavioral topics your targets publish or candidates report, and map each to a story you have.

What it covers:

What Palantir publishes
Company-wide and engineering-wide guidance
Values and mission
Culture and fit conversations
Career-history interviews
Be real, not rehearsed
Your story map

Palantir’s Getting Hired page, written for its candidates in general and not for forward deployed software engineers alone, says: “We’ll be asking you questions about how you’ve executed, challenged yourself, motivated others, and made judgments—as well as where you’ve failed in the past.” Source 1Getting Hired - Palantir CareersPublisherPalantir TechnologiesSource typecompany hiring page That sentence is a list of stories you need before the onsite. This lesson builds that list for each of your targets and maps it to stories you have; the evidence map covers how much weight each candidate report can carry.

Through this module you follow Maya, an integrations engineer who became the deployed engineer at a company that sells scheduling and payroll software to restaurant groups. She also shipped an assistant that answers managers’ scheduling-rule questions from a customer’s own handbook. Maya is fictional, and so are her employer and its customers.

What Palantir publishes

The page doesn’t say which interview asks which topic, so have a story for each, and be ready to tell one in the same hour as a technical problem. Palantir’s early-talent timeline describes its virtual onsite’s learning and decomposition interviews as “consisting of behavioral and technical questions.” Source 2Students | Palantir Careers (timeline image: RecruitingTimeline_V3.jpg)PublisherPalantirSource typecompany hiring page That graphic is for early-career hires, but one Government-track candidate wrote on Reddit, in December 2025, that their decomposition and learning rounds each split into 15 behavioral minutes and 45 technical ones. Source 3Palantir FDSE Full Interview Loop Process (post by u/Not_the_Sauron)PublisherReddit r/csMajorsSource typecandidate report on Reddit

Read each topic for what it must prove in customer work, and for the question that follows your answer. These readings and probes are ours, not Palantir’s.

Executed. A result at a customer, in their systems, under constraints you didn’t set. Expect: “What would have happened if you’d left halfway?” Practice: a project you owned end to end.
Challenged yourself. Something you couldn’t do at the start and could at the end. Expect: “What did you get wrong first?” Practice: outside your comfort zone.
Motivated others. People who didn’t report to you, often at the customer: their IT team, their store managers. Expect: “What was in it for them?” Practice: a group that didn’t report to you.
Made judgments. A call made before the facts were in: what you knew, and what you didn’t. Expect: “What would have changed your mind?” Practice: a decision with too little data.
Failed. Your mistake, what it cost the customer, and what you do differently now. Expect: “Who found it?” Practice: a failure that was your fault.

Prepare the probe’s answer with the story. Answering in about a minute builds the short version and its follow-ups.

The short written prompts on Palantir’s New Grad FDSE application, such as a time you changed your mind, are a different exercise, covered in the bridge story.
