OpenAI Front End Interview Questions

Latest version on GreatFrontEnd

Find the latest version of this page on GreatFrontEnd's OpenAI Front End Interview Guide.

OpenAI's frontend loop has a full-stack tech screen (DSA + full-stack system design) followed by a more domain-focused (FE-leaning) onsite. The tech screen is the same for everyone regardless of specialization — expect a LeetCode-style round even if you're applying for a frontend role.

Interview process​

  • Tech screen: 1 hour DSA coding + 1 hour full-stack system design.
  • Onsite: More domain-focused — frontend if you're interviewing for a frontend role.

JavaScript coding questions​

  • DSA coding (1 hour, LeetCode-style) — same screen for everyone regardless of role specialisation.

User interface coding questions​

  • React question: build a UI that pulls from one of their internal APIs (one reported variant returned poetry — straightforward fetch + render with some interaction).

System design questions​

  • Design an older variant of ChatGPT (the most commonly reported question).
  • Full-stack system design (tech screen, 1 hour).

The OpenAI tech screen is full-stack — 1 hour DSA coding + 1 hour full-stack system design. The onsite is then more domain-focused, so frontend if you're going for a FE role. Don't skip DSA prep even for a frontend interview here.

30th Jul 2025:

Cleared my OpenAI first pair of rounds a couple months back. The React question was pulling from one of their APIs that returned poetry or something — straightforward fetch + render with some interaction. The system design round was basically designing an older variant of ChatGPT.
