The OpenAI FDE Interview Loop
The OpenAI FDE interview process emphasizes understanding candidates' problem-solving approaches, decision-making, and communication skills. Preparation should align with OpenAI's guidelines, which highlight the importance of collaboration and adaptability. Candidates are advised to practice both with and without AI tools, as expectations vary by interview format. Reports from previous candidates can provide insights into the process, but they should not be taken as definitive. Effective communication and a clear demonstration of results are crucial throughout the interview stages.
A candidate spent three weekends preparing for what they expected to be a five-hour take-home assignment. Based on several online accounts of OpenAI FDE interviews, they practised building projects with an AI coding assistant available throughout. The recruiter's email then confirmed a different format: a live pair-programming session where AI assistance was not allowed.
The practice was still useful, but it had not prepared the candidate for the constraints of the actual interview. They had prepared for the interview they had read about, not the one they were invited to.
A more reliable approach is to use OpenAI's official guidance as a starting point, treat candidate reports as supplementary information, and adapt preparation once the recruiter confirms the interview format and permitted tools. This lesson outlines the interview process using that approach. The next five lessons examine each stage in detail.
What does OpenAI’s interview guide say?
OpenAI publishes an interview guide that describes an example process and says plainly that individual experiences may differ. It is not specific to the FDE role.
Stage | What the Guide Describes |
Application and résumé review | The recruiting team typically replies within a week |
Introductory calls | A conversation with the hiring manager or a recruiter about experience, motivations, and goals |
Skills-based assessment | Formats vary by team and may include pair coding, take-home projects, or technical tests; some roles have more than one; the recruiting team provides prep |
Final interviews | Virtual by default, with an option to interview onsite in San Francisco; typically 4–6 hours with 4–6 people over 1–2 days, focused on the candidate’s area of expertise |
Decision | Typically within a week of the final interviews; the recruiter may ask for references |
