OpenAI forward deployed engineer interview

By FDE Interview Prep, a SourceStrongAI company

OpenAI’s San Francisco FDE posting says how its FDEs measure success: production adoption, measurable workflow impact, and eval-driven feedback that changes product and model roadmaps. ^[1]Source 1Forward Deployed Engineer (FDE) - SF | OpenAIPublisherOpenAISource typecompany job posting Prepare every round against that list. The fullest public reports point the same way: one candidate for the FDE title reported a take-home and then a live team discussion of it, interviewing in May 2026, and a Glassdoor reviewer who accepted an offer for a neighboring title, interviewing in August 2025, listed a take-home ahead of a technical and a sales round onsite. ^{[17, 18]}Source 17OpenAI Forward Deployed Engineer Interview ExperiencePublisherAced (formerly Exponent)Source typecandidate’s personal write-upSource 18OpenAI AI Deployment Engineer Interview QuestionsPublisherGlassdoor (anonymous interview review)Source typecandidate’s personal write-up So plan to build something, then explain it to people who push back.

OpenAI publishes no FDE loop, so this guide pieces one together from its interview guide, its postings, its FDE lead’s own words and those reports, and keeps what OpenAI says apart from what people report. For how FDE loops run across employers, start with the FDE interview guide.

Which OpenAI role you are interviewing for

OpenAI hires under the exact title Forward Deployed Engineer, in a department called Forward Deployed Engineering, and its San Francisco posting says the FDE owns discovery, technical scoping, system design, build and production rollout alongside strategic customers. ^{[1, 2, 19]}Source 1Forward Deployed Engineer (FDE) - SF | OpenAIPublisherOpenAISource typecompany job postingSource 2Forward Deployed Engineer (FDE) - SF (Ashby)PublisherOpenAI (Ashby job board)Source typecompany job postingSource 19Applied AI ArchitectPublisherOpenAI (Ashby)Source typecompany job posting It also posts a separate title, Forward Deployed Software Engineer, in San Francisco, New York and Seattle. ^{[3, 4]}Source 3Forward Deployed Software Engineer - SF (Ashby)PublisherOpenAI (Ashby job board)Source typecompany job postingSource 4Forward Deployed Software Engineer - NYC (Ashby)PublisherOpenAI (Ashby job board)Source typecompany job posting Deployment Lead roles (titled Technical Deployment Lead until late September 2026) sit in the same department and run day-to-day execution across FDEs, researchers and customer engineers. ^{[6, 7]}Source 6Technical Deployment Lead, Semiconductors- SF (Ashby)PublisherOpenAI (Ashby job board)Source typecompany job postingSource 7Technical Deployment Lead - Singapore (Ashby)PublisherOpenAI (Ashby job board)Source typecompany job posting A government FDE sits in the OpenAI for Gov team. ^[5]Source 5Forward Deployed Engineer, Gov (Ashby)PublisherOpenAI (Ashby job board)Source typecompany job posting

Three nearby titles matter for reading the reports below. Most Applied AI Architect and Applied AI Engineer postings sit in a Go To Market department, not in Forward Deployed Engineering. ^{[2, 19]}Source 2Forward Deployed Engineer (FDE) - SF (Ashby)PublisherOpenAI (Ashby job board)Source typecompany job postingSource 19Applied AI ArchitectPublisherOpenAI (Ashby)Source typecompany job posting A Glassdoor reviewer who went through OpenAI’s loop, and a Blind commenter describing the rounds they expected, both named AI Deployment Engineer, which is not the FDE title either. ^{[18, 20]}Source 18OpenAI AI Deployment Engineer Interview QuestionsPublisherGlassdoor (anonymous interview review)Source typecandidate’s personal write-upSource 20Anthropic/OpenAI FDE Interview loop -- same as SWE?PublisherBlind (teamblind.com)Source typecandidate report on Blind Treat them as a view of a neighboring loop.

The function is young. Colin Jarvis posted in January 2025 that he would lead OpenAI’s new Forward Deployed Engineering function. ^[21]Source 21Colin Jarvis on XPublisherColin Jarvis (OpenAI), via XSource typecompany website The Engineering Leadership newsletter reported, in August 2026, that the FDE org started with two people and had grown to around 140. ^[22]Source 22Inside OpenAI’s Forward Deployed Engineer RolePublisherEngineering Leadership (Gregor Ojstersek)Source typenews report Our reading: the loop is young and the team grew fast, so the process may have changed along the way. That may be why the public reports are few and why they disagree.

Read your own posting line by line before anything else, because the variants ask for different things: the Healthcare postings ask for work with safeguards for PHI and HIPAA, and the Tokyo postings interview in Japanese and English. ^{[11, 12, 23, 24]}Source 11Forward Deployed Engineer - Tokyo (Ashby)PublisherOpenAI (Ashby job board)Source typecompany job postingSource 12Manager, Forward Deployed Engineer - Tokyo (Ashby)PublisherOpenAI (Ashby job board)Source typecompany job postingSource 23Forward Deployed Engineer (FDE), Healthcare - SF (Ashby)PublisherOpenAI (Ashby job board)Source typecompany job postingSource 24Forward Deployed Engineer (FDE), Healthcare - NYC (Ashby)PublisherOpenAI (Ashby job board)Source typecompany job posting How to read an FDE job posting shows how.

The loop, pieced together

Here is each stage in order: what OpenAI’s general guide says about it (the guide is not written for FDE roles), and which reports mention it, with a link to how to prepare.

• Résumé review. OpenAI says the recruiting team takes about a week to reply. ^[25]Source 25Interview Guide | OpenAIPublisherOpenAISource typecompany hiring page
• Recruiter screen. OpenAI says the introductory call is with the hiring manager or a recruiter, and that you hear within a week whether you have progressed. ^{[25, 26]}Source 25Interview Guide | OpenAIPublisherOpenAISource typecompany hiring pageSource 26OpenAI interview guide (Wayback Machine capture)PublisherOpenAI (archived by Internet Archive)Source typearchived company page One candidate for the Forward Deployed Software Engineer title posted about this call in February 2025, and a Glassdoor reviewer for the FDE title had it that same month. ^{[27, 28, 29, 30]}Source 27OpenAI Forward Deployed Software Engineer (comment by u/aksss123)PublisherReddit r/leetcodeSource typecandidate report on RedditSource 28OpenAI Forward Deployed Software Engineer (comment by u/aksss123)PublisherReddit r/leetcodeSource typecandidate report on RedditSource 29OpenAI Forward Deployed Software Engineer (comment by u/aksss123)PublisherReddit r/leetcodeSource typecandidate report on RedditSource 30OpenAI Forward Deployed Engineer Interview QuestionsPublisherGlassdoor (anonymous interview review)Source typecandidate’s personal write-up The recruiter screen below uses both.
• Skills assessment. OpenAI says it may be pair coding, a take-home or a technical test, and possibly more than one. ^[25]Source 25Interview Guide | OpenAIPublisherOpenAISource typecompany hiring page One FDE candidate reported both a take-home and an AI-enabled coding screen, interviewing in May 2026. ^[17]Source 17OpenAI Forward Deployed Engineer Interview ExperiencePublisherAced (formerly Exponent)Source typecandidate’s personal write-up Prepare them with the take-home and coding sections.
• The take-home defense. OpenAI doesn’t describe one. One candidate reported a live team discussion of their take-home, the same May 2026 report as above. ^[17]Source 17OpenAI Forward Deployed Engineer Interview ExperiencePublisherAced (formerly Exponent)Source typecandidate’s personal write-up
• Final interviews. OpenAI says they are virtual by default, and its example has four to six hours of them with four to six people over one or two days. ^[25]Source 25Interview Guide | OpenAIPublisherOpenAISource typecompany hiring page Candidates for other OpenAI titles reported a sales round and a presentation pitched to executives: see the final rounds. ^{[18, 31]}Source 18OpenAI AI Deployment Engineer Interview QuestionsPublisherGlassdoor (anonymous interview review)Source typecandidate’s personal write-upSource 31OpenAI Deployment Strategist Interview ExperiencePublisherAced (formerly Exponent)Source typecandidate’s personal write-up
• Decision. OpenAI says to expect it within one week of the finals, and the recruiter may ask for references then. ^[25]Source 25Interview Guide | OpenAIPublisherOpenAISource typecompany hiring page

One more account is weaker: in a Blind thread whose original poster asked how to prepare for OpenAI’s FDE role, a commenter wrote in June 2026 that a take-home “they” sent was a design doc, without naming the company or the role. ^[32]Source 32What to prepare for a Forward Deployed Engineer role at OpenAI?PublisherBlindSource typecandidate report on Blind

No one publishes how often any of these shapes happens, and the reports span more than a year and several titles. The evidence map lesson shows how to weigh this kind of evidence for any company.

How to prepare for each stage

This is our method, built from what OpenAI publishes and what the reports name. It is not a rubric OpenAI publishes.

The recruiter screen

Make every answer carry a signal: something you built, for whom, and what changed. A Glassdoor reviewer for the FDE title reported a recruiter screen that the recruiter cut short, followed the next day by a rejection for “lacked signals”, interviewing in February 2025. ^[30]Source 30OpenAI Forward Deployed Engineer Interview QuestionsPublisherGlassdoor (anonymous interview review)Source typecandidate’s personal write-up You can’t control a short call, but you can put your evidence in its first minute.

OpenAI’s guide says to be ready to discuss your work and academic experience, motivations and goals, and recommends reading up on OpenAI’s recent updates, especially those for the team you are interviewing for. ^[26]Source 26OpenAI interview guide (Wayback Machine capture)PublisherOpenAI (archived by Internet Archive)Source typearchived company page So read what OpenAI has shipped lately for that team, then open with something in this shape, said in about a minute:

I’m a [role] who has put [system] in front of [customer type]. The last one: [problem], [what I built], measured by [adoption or outcome]. I’ve built with the OpenAI API on [project], where I hit [a real limit]. I want FDE because [reason from your own work].

One candidate for the Forward Deployed Software Engineer title reported, in February 2025, being asked about customer-facing experience, OpenAI’s APIs and language preference, and wrote that “apparently they prefer python then JavaScript secondary”. ^{[27, 28, 29]}Source 27OpenAI Forward Deployed Software Engineer (comment by u/aksss123)PublisherReddit r/leetcodeSource typecandidate report on RedditSource 28OpenAI Forward Deployed Software Engineer (comment by u/aksss123)PublisherReddit r/leetcodeSource typecandidate report on RedditSource 29OpenAI Forward Deployed Software Engineer (comment by u/aksss123)PublisherReddit r/leetcodeSource typecandidate report on Reddit So have a concrete answer for the first two, and have Python ready for the coding round. Practice with your background in about a minute, which is free, then What customer-facing experience do you have?, Which of our APIs have you built with? and Why forward deployed engineering?. The recruiter screen post covers the rest of this call.

The take-home and its defense

Scope it, build a thin working version, evaluate it, then defend it. The posting says FDEs measure success partly by eval-driven feedback, so show how you know your build works, not only that it runs. ^[1]Source 1Forward Deployed Engineer (FDE) - SF | OpenAIPublisherOpenAISource typecompany job posting The May 2026 candidate wrote that a lot of the evaluation seemed to come down to explaining their decisions clearly and tying them back to customer needs. ^[17]Source 17OpenAI Forward Deployed Engineer Interview ExperiencePublisherAced (formerly Exponent)Source typecandidate’s personal write-up

Here is one exchange for the reported prompt, semantic search over products, to show the level of answer that ties a decision to evidence:

Interviewer: Why embeddings alone?

You: It was the fastest way to a first version I could measure. My eval shows where it breaks: queries with a price limit, because similarity can’t enforce a cap. Next I’d parse the limit and filter on price before ranking.

The shape is the choice, the evidence from your own eval, and the next fix. To warm up, build retrieval over text files with no libraries, which is free and the same kind of problem. Rehearse the defense out loud with defend your take-home design and what would you change with another day?, and answer how do you know your AI system works? before anyone asks it. The OpenAI take-home post walks through the whole routine, with a runnable hit-rate and MRR harness and a submission checklist, and the walkthrough video post has a script for the recording.

Coding, with or without AI

The guide names what engineering interviews look for: well-designed solutions, high-quality code, optimal performance and good test coverage, plus communication. ^{[25, 26]}Source 25Interview Guide | OpenAIPublisherOpenAISource typecompany hiring pageSource 26OpenAI interview guide (Wayback Machine capture)PublisherOpenAI (archived by Internet Archive)Source typearchived company page The May 2026 candidate reported that even in the AI-enabled coding round, the interviewers wanted time complexity and memory discussed. ^[17]Source 17OpenAI Forward Deployed Engineer Interview ExperiencePublisherAced (formerly Exponent)Source typecandidate’s personal write-up So say the complexity of what you write, and when it would matter, without waiting to be asked; state the complexity of your solution drills exactly that, and fixing retrieval that misses the top results, which is free, is the AI-shaped version.

Ask your recruiter which rounds allow AI tools, since the guide says it varies. ^[25]Source 25Interview Guide | OpenAIPublisherOpenAISource typecompany hiring page Where they are allowed, be ready to say how you use them and where you don’t trust them: how you use AI coding tools. What FDE coding rounds test and the post on AI-assisted coding rounds cover both kinds of round.

System design and architecture

One poster on Blind wrote “traditional system design interview” about the FDE loop, and another, for the Forward Deployed SWE title, wrote before interviewing that the recruiter said the architecture round has front end. ^{[32, 33]}Source 32What to prepare for a Forward Deployed Engineer role at OpenAI?PublisherBlindSource typecandidate report on BlindSource 33OpenAI Forward Deployed SWE RolePublisherBlind (teamblind.com)Source typecandidate report on Blind So prepare an AI-shaped design end to end, browser included. Here is a sketch you should be able to draw for an assistant that answers questions over a customer’s documents, from the user’s screen inward:

1. Browser. The answer streams in token by token over server-sent events, and each citation renders inline and opens its source passage.
2. Gateway. Single sign-on through the customer’s identity provider, so every request carries who the user is.
3. App server. It assembles the prompt from the question, the retrieved passages and the instructions.
4. Retrieval. Search over the customer’s documents, filtered by what this user is allowed to read before ranking, not after.
5. Model API. The call to the model, with a timeout and a fallback message the user can act on.
6. Logging. Each question, the passages used and the answer, feeding an eval set you rerun before every change.

Then name the failure modes before you are asked, with a sentence for each:

• Slow first token. “People judge speed by when the first words appear, so I stream, keep the prompt lean and track time to first token as its own number.”
• Prompt injection through a retrieved document. “A document can carry instructions, so retrieved text is treated as data, and the model gets no tool that acts without a check outside the model.”
• A stale index. “If a policy changes and the index doesn’t, the answer is confidently wrong, so I track when each source was last indexed and show that date beside the citation.”

Practice the pieces with verifiable citations, why the assistant can’t be right every time and defending an agent against prompt injection, each of them free, and an eval harness for a support agent. Enterprise system design is not ‘design a social network’ covers the classic enterprise version, and the RAG system design post goes deeper on retrieval.

The final rounds: customers, leaders and your own work

Prepare to present to an executive even if you are told the room is internal. One candidate for Technical Deployment Lead reported being told the final presentation was for internal teammates and then being asked to present as if to executive customers, interviewing in June 2026. ^[31]Source 31OpenAI Deployment Strategist Interview ExperiencePublisherAced (formerly Exponent)Source typecandidate’s personal write-up A Glassdoor reviewer for AI Deployment Engineer, a neighboring title, listed a sales round onsite, interviewing in August 2025. ^[18]Source 18OpenAI AI Deployment Engineer Interview QuestionsPublisherGlassdoor (anonymous interview review)Source typecandidate’s personal write-up Open like this:

You asked for [their outcome, in their words]. We built [what it does, in a sentence]. On [their own data], it [result against the measure you agreed]. There is a decision I need from you today: [the risk, and the choice].

When the room changes from engineers to executives, cut rather than compress: the architecture goes to an appendix, and a single slide carries the adoption measure and the risk. Present a past project to a mixed audience practices the switch, and From discovery call to technical proposal teaches the proposal behind it.

The same Glassdoor reviewer, who accepted an offer, listed one question from their loop: what the reason would be if they failed in six months. ^[18]Source 18OpenAI AI Deployment Engineer Interview QuestionsPublisherGlassdoor (anonymous interview review)Source typecandidate’s personal write-up Prepare for it by naming a real risk, then how you guard against it:

The likeliest reason would be that I built what the first stakeholder asked for rather than what the people doing the work adopted. How I guard against it: I watch the work being done before I build, I agree an adoption measure with the customer before I start, and I put a first version in front of real users early.

A failure that was yours, which is free, and your first month with a new customer practice both halves of that answer.

For the hiring-manager conversation, use what the head of the function says he values. Jarvis said on a South Park Commons panel posted in May 2026 that the relentless pursuit of value makes a good FDE. ^[34]Source 34The Future of Forward Deployed Engineering | OpenAI, Ramp, Nominal, DatalandPublisherSouth Park Commons (YouTube)Source typerecorded talk or interview He named as a failure pattern people who love the form of what they built more than its function, and said the best FDEs will tear a solution up and build something completely different when users do not use it. ^[34]Source 34The Future of Forward Deployed Engineering | OpenAI, Ramp, Nominal, DatalandPublisherSouth Park Commons (YouTube)Source typerecorded talk or interview So bring that story, in this shape:

I built [X] for [user]. Adoption told me it was wrong: [the signal you saw]. I threw it out and built [Y], and here is what changed: [measure].

Practice it with Tell me about work you threw away, and use the project deep dive post to hold up under follow-up questions.

The same panel shows what else the team values. Jarvis said the FDE unit works only about 10 engagements at a time and has to say no more often than yes. ^[34]Source 34The Future of Forward Deployed Engineering | OpenAI, Ramp, Nominal, DatalandPublisherSouth Park Commons (YouTube)Source typerecorded talk or interview So be ready for “when would you not put an FDE on this?”, with when a customer doesn’t need an embedded engineer and a time you said no to a senior customer, which is free. The Engineering Leadership newsletter reported, in August 2026, that the FDE org sits between go-to-market and product and research, which fits the posting’s “eval-driven feedback that changes product and model roadmaps”. ^{[1, 22]}Source 1Forward Deployed Engineer (FDE) - SF | OpenAIPublisherOpenAISource typecompany job postingSource 22Inside OpenAI’s Forward Deployed Engineer RolePublisherEngineering Leadership (Gregor Ojstersek)Source typenews report Bring a story where what you saw in the field changed a product: field feedback that changed a roadmap.

Every question we have tied to OpenAI, with who reported it, is on OpenAI’s FDE interview questions.

If you come from data or backend engineering

Your security, authorization and governance experience is work some OpenAI postings ask for by name. The Healthcare postings ask you to build with safeguards for PHI, HIPAA, privacy, security, authorization, governance and auditability. ^{[23, 24]}Source 23Forward Deployed Engineer (FDE), Healthcare - SF (Ashby)PublisherOpenAI (Ashby job board)Source typecompany job postingSource 24Forward Deployed Engineer (FDE), Healthcare - NYC (Ashby)PublisherOpenAI (Ashby job board)Source typecompany job posting The Legal and Financial Services postings ask for customer-facing ownership in financial services or adjacent regulated industries. ^{[35, 36]}Source 35Forward Deployed Engineer (FDE), Financial Services- NYC (Ashby)PublisherOpenAI (Ashby job board)Source typecompany job postingSource 36Forward Deployed Engineer (FDE), Legal-NYC (Ashby)PublisherOpenAI (Ashby job board)Source typecompany job posting Our reading: regulated customers are where that experience transfers most directly, so lead with it. If you hold a clearance, say so early: the Gov FDE posting, in the OpenAI for Gov team, lists an active TS/SCI clearance or equivalent among its qualifications. ^[5]Source 5Forward Deployed Engineer, Gov (Ashby)PublisherOpenAI (Ashby job board)Source typecompany job posting

A recruiter may suggest the switch. One Blind poster reported, in July 2026, that after a backend software engineer screen went really well in their view, the recruiter said that position was filled and that they might be a strong fit for FDE. ^[37]Source 37OpenAI Forward Deployed Engineer vs Backend Software EngineerPublisherBlind (teamblind.com)Source typecandidate report on Blind If that happens to you, ask whether your technical screen carries over to the FDE loop.

Coming from outside the customer’s industry is not the gap it looks like. The Engineering Leadership newsletter reported, in August 2026, that Jarvis said OpenAI ideally wants FDEs with domain expertise in the customer’s field, and that OpenAI deliberately mixes in FDEs from outside that industry, because an outsider is more likely to challenge the status quo. ^[22]Source 22Inside OpenAI’s Forward Deployed Engineer RolePublisherEngineering Leadership (Gregor Ojstersek)Source typenews report Have a story ready about becoming useful in an unfamiliar domain fast.

The gap to close is evals and retrieval. Work through retrieval with no libraries, how do you know your AI system works? and why the assistant can’t be right every time, each of them free. If you are also preparing for Palantir, our Palantir guide spends longest on the decomposition round, while the fullest OpenAI reports center on building something and defending it, so practice both shapes rather than one.

The OpenAI Deployment Company is a separate door

OpenAI launched the OpenAI Deployment Company in May 2026 and agreed to acquire Tomoro, saying the deal would bring approximately 150 experienced FDEs and deployment specialists. ^[38]Source 38OpenAI launches the OpenAI Deployment Company to help businesses build around intelligence | OpenAIPublisherOpenAISource typecompany blog It hires on its own careers page, where its postings call it “DeployCo”. ^{[14, 15]}Source 14Careers | OpenAI Deployment Company | OpenAI Deploy Co.PublisherOpenAI Deployment CompanySource typecompany hiring pageSource 15Forward Deployed Engineer - USPublisherOpenAI Deployment Company (Ashby job board)Source typecompany job posting The Engineering Leadership newsletter reported that Jarvis said OpenAI intends to keep its internal FDE org relatively small while it expands the Deployment Company. ^[22]Source 22Inside OpenAI’s Forward Deployed Engineer RolePublisherEngineering Leadership (Gregor Ojstersek)Source typenews report

Its US posting describes a founding FDE who works as a technical lead on customer deployments, will “ramp quickly toward management responsibilities”, and makes “disciplined standardization-versus-customization decisions instead of defaulting to bespoke work”. ^[15]Source 15Forward Deployed Engineer - USPublisherOpenAI Deployment Company (Ashby job board)Source typecompany job posting That last line is a gift for interview prep. Bring a pair of stories: a time you chose the standard build over a custom one, and a time you did the opposite. Frame them like this: “I default to the standard build and customize only where the customer’s workflow breaks without it. Here is one of each.” Practice with custom build or product change.

For teams that apply together, its “Apply with Your Team” listing says the interviews include individual conversations and a technical assessment, alongside a working session on how the team solves problems together, and that each person is held to the same bar as other candidates for the role. ^[39]Source 39Apply with Your TeamPublisherOpenAI Deployment Company (Ashby job board)Source typecompany job posting It does not describe the loop for a single applicant, and we found no candidate report from it. The Deployment Company post has the rest.

Pay and travel, in short

The posted bands are listed on this page. For a second view, in H-1B filings certified from October 2024 to June 2026, OpenAI’s eight certified forward-deployed filings had a median offered base wage of $225,500, taking the lower bound of each filing’s range, under titles such as “Member of Forward Deployed Staff”. ^{[40, 41]}Source 40LCA_Disclosure_Data_FY2026_Q3.xlsx (DOL OFLC LCA disclosure data)PublisherUS Department of Labor, Office of Foreign Labor CertificationSource typeUS Department of Labor filing dataHow we used this dataSource 41LCA_Disclosure_Data_FY2025_Q4.xlsx (DOL OFLC LCA disclosure data)PublisherUS Department of Labor, Office of Foreign Labor CertificationSource typeUS Department of Labor filing dataHow we used this data Filings record base wage only, not equity. The FDE salary guide sets these against other employers.

Plan for travel. The San Francisco posting says travel up to 50% is required. ^[1]Source 1Forward Deployed Engineer (FDE) - SF | OpenAIPublisherOpenAISource typecompany job posting The Engineering Leadership newsletter reported, in August 2026, that OpenAI generally tells new FDEs to expect around 50% of their time on customer sites, and that some in the UAE and Japan are on site around 80% of the time. ^[22]Source 22Inside OpenAI’s Forward Deployed Engineer RolePublisherEngineering Leadership (Gregor Ojstersek)Source typenews report Ask your recruiter what your team expects; the travel post has the questions.

Questions to ask your recruiter

OpenAI’s guide says your preparation materials explain what is allowed with AI tools, and to ask your recruiter if you are unsure. ^{[25, 26]}Source 25Interview Guide | OpenAIPublisherOpenAISource typecompany hiring pageSource 26OpenAI interview guide (Wayback Machine capture)PublisherOpenAI (archived by Internet Archive)Source typearchived company page The same goes for everything this guide could not pin down, so take this list to your first call.

A prep plan by stage

Prepare each stage as a block, so the order your loop takes stops mattering. The table below pairs each stage with what to practice out loud and what to read, and most rows start with a free item. Every question tagged OpenAI is on one page. Everything in the table is free except the items marked Pro, which are in Pro; Pro starts with a 7-day free trial.

Practice the part you cannot do alone

You can build a take-home by yourself. The live part, where someone asks what you would ask the customer or why you chose one approach, is the part that goes wrong under pressure. The free case is a city’s permit backlog, not a model deployment, and that is fine: it trains the moves a take-home defense and an executive presentation need, which are scoping with an owner who is not technical, choosing a first version, and saying how you would know it works.

The free practice case puts you in front of an AI customer with a vague problem on a 10-minute clock: you scope it, propose a first version and say how you would know it works, then a scorecard shows what you asked and what you missed. It is free with a sign-in. In Pro, the claim intake case asks you to put a model the customer has already licensed into production, the closest of our cases to deployment work at an AI lab.

Practice for OpenAI

What this guide recommends. The Pro tag marks what is in Pro; a Pro question’s framework is still free, and its model answer is in Pro.

Questions people ask

What is the OpenAI FDE interview process?

OpenAI does not publish an FDE-specific process. Its general interview guide, for all roles, describes résumé review, introductory calls with a recruiter or the hiring manager, a skills-based assessment that may be pair coding, a take-home or a technical test (sometimes more than one), final interviews (in its example, four to six hours with four to six people over one or two days, virtual by default), and a decision within one week of the finals. It does not list the rounds for FDE roles.^{[25, 26]}Source 25Interview Guide | OpenAIPublisherOpenAISource typecompany hiring pageSource 26OpenAI interview guide (Wayback Machine capture)PublisherOpenAI (archived by Internet Archive)Source typearchived company page

Does the OpenAI FDE interview have a take-home, and what have candidates reported?

It may. OpenAI’s guide lists take-home projects as one possible format, varying by team. One candidate reported a one-week take-home for an FDE role, interviewing in May 2026, followed by a live team discussion of it. A Blind commenter with a recruiter call scheduled for the AI Deployment Engineer title expected, in March 2026, a take-home of about 5 hours with a video walkthrough.^{[17, 20, 25]}Source 17OpenAI Forward Deployed Engineer Interview ExperiencePublisherAced (formerly Exponent)Source typecandidate’s personal write-upSource 20Anthropic/OpenAI FDE Interview loop -- same as SWE?PublisherBlind (teamblind.com)Source typecandidate report on BlindSource 25Interview Guide | OpenAIPublisherOpenAISource typecompany hiring page

Can I use ChatGPT or other AI tools in OpenAI interviews?

It depends on the interview. OpenAI’s guide says some formats intentionally allow AI tools and others are designed to assess problem-solving without them, that your preparation materials explain what is allowed, and to ask your recruiter if you are unsure. It does not say which FDE rounds are which.^{[25, 26]}Source 25Interview Guide | OpenAIPublisherOpenAISource typecompany hiring pageSource 26OpenAI interview guide (Wayback Machine capture)PublisherOpenAI (archived by Internet Archive)Source typearchived company page

What does OpenAI look for in forward deployed engineers?

The guide says engineering interviews look for well-designed solutions, high-quality code, optimal performance and good test coverage, plus communication and collaboration. The FDE posting measures success by production adoption, workflow impact and eval-driven feedback. Colin Jarvis, who leads the function, said in a panel posted in May 2026 that the relentless pursuit of value is what makes a good FDE.^{[1, 25, 26, 34]}Source 1Forward Deployed Engineer (FDE) - SF | OpenAIPublisherOpenAISource typecompany job postingSource 25Interview Guide | OpenAIPublisherOpenAISource typecompany hiring pageSource 26OpenAI interview guide (Wayback Machine capture)PublisherOpenAI (archived by Internet Archive)Source typearchived company pageSource 34The Future of Forward Deployed Engineering | OpenAI, Ramp, Nominal, DatalandPublisherSouth Park Commons (YouTube)Source typerecorded talk or interview

The Legal and Financial Services postings say travel up to 50% may be required.^{[1, 35, 36]}Source 1Forward Deployed Engineer (FDE) - SF | OpenAIPublisherOpenAISource typecompany job postingSource 35Forward Deployed Engineer (FDE), Financial Services- NYC (Ashby)PublisherOpenAI (Ashby job board)Source typecompany job postingSource 36Forward Deployed Engineer (FDE), Legal-NYC (Ashby)PublisherOpenAI (Ashby job board)Source typecompany job posting

What is the difference between OpenAI’s FDE and FDSWE roles?

They are separate postings. The FDE posting describes leading end-to-end deployments of frontier models with strategic customers and asks for 5+ years including customer-facing work. The Forward Deployed Software Engineer posting, in San Francisco, New York and Seattle, lists 7+ years of full-stack engineering among its qualifications. Neither says how their interviews differ.^{[1, 2, 3, 4, 42]}Source 1Forward Deployed Engineer (FDE) - SF | OpenAIPublisherOpenAISource typecompany job postingSource 2Forward Deployed Engineer (FDE) - SF (Ashby)PublisherOpenAI (Ashby job board)Source typecompany job postingSource 3Forward Deployed Software Engineer - SF (Ashby)PublisherOpenAI (Ashby job board)Source typecompany job postingSource 4Forward Deployed Software Engineer - NYC (Ashby)PublisherOpenAI (Ashby job board)Source typecompany job postingSource 42Forward Deployed Engineer (FDE) - Seattle (Ashby)PublisherOpenAI (Ashby job board)Source typecompany job posting

Is the OpenAI Deployment Company the same as OpenAI’s FDE team?

No. OpenAI launched the OpenAI Deployment Company in May 2026 as a company it majority-owns and controls, and it hires FDEs through its own careers page. For teams that apply together, it says the interviews include individual conversations, a technical assessment and a working session on how the team solves problems together. It does not describe the loop for a single applicant.^{[14, 15, 38, 39]}Source 14Careers | OpenAI Deployment Company | OpenAI Deploy Co.PublisherOpenAI Deployment CompanySource typecompany hiring pageSource 15Forward Deployed Engineer - USPublisherOpenAI Deployment Company (Ashby job board)Source typecompany job postingSource 38OpenAI launches the OpenAI Deployment Company to help businesses build around intelligence | OpenAIPublisherOpenAISource typecompany blogSource 39Apply with Your TeamPublisherOpenAI Deployment Company (Ashby job board)Source typecompany job posting
