The Interview Loop Overview
Prepare for OpenAI’s FDE interview process by reviewing its example stages: application review, introductory calls, skills assessments, final interviews, and a decision. Treat OpenAI’s official guidance and your own assessment instructions as the authority. Practice problem-solving, communication, technical reasoning, and customer judgment using evidence you can substantiate. Clarify uncertain tool permissions with your recruiter. Assess preparation gaps, choose targeted practice, define progress checks, and schedule reviews within the time available.
Most candidates prepare for the interview they imagine. The ones who do well prepare for the one OpenAI describes, then adjust as soon as the recruiter sends real instructions. This chapter walks through each stage of the FDE loop and what it tests. This lesson is the map: what OpenAI’s own guide says, what the FDE loop typically includes, what each stage looks for, and how to turn that into a preparation plan.
What does OpenAI’s guide say?
OpenAI’s interview guide presents an example process with five parts, and it says plainly that an individual experience may differ.
Application and résumé review: The recruiting team reviews your application, typically within a week.
Introductory calls: You discuss your experience, motivations, and goals with a recruiter or hiring manager.
Skills-based assessments: The team shares details and preparation materials for an assessment relevant to the role.
Final interviews: Interviewers focus on your area of expertise and on how you solve problems. The guide says candidates typically spend 4–6 hours with 4–6 people over 1–2 days.
Decision: You hear back, typically within a week, and the recruiter may ask for references.
Assessment formats vary by team and may include pair coding, take-home projects, or technical tests, and some roles ask for more than one. The guide says interviews look at how you approach problems, make decisions, and communicate your reasoning. For engineering interviews, OpenAI generally looks for well-designed solutions, high-quality code, optimal performance, and good test coverage.
Two rules follow. The guide is an example, so no stage is guaranteed. And the materials for your assessment govern that assessment, so when something is unclear, especially which tools you may use, ask the recruiter before the interview.
What does the FDE loop typically include?
The official guide isn’t FDE-specific. An FDE loop typically includes a take-home with a recorded walkthrough, followed by a technical deep dive. Treat that as ...
