OpenAI Front End Interview Questions
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.

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.
