What interview questions does OpenAI ask?

Candidates have reported 87 questions from OpenAI interviews to TrueInterview: 28 algorithm, 22 system design, 19 low-level design and 17 ai coding. Each one is filed under the round it came up in, with the month it was reported where a candidate gave one, and opens in the workspace that format calls for — an editor judged against hidden tests for coding and SQL, a whiteboard for system design.

How recent are these OpenAI interview questions?

The most recent OpenAI question on this page was reported in September 2026. A question shows the month a candidate reported it whenever that is known, so an entry that has gone stale is visible as one rather than presented as current.

Which OpenAI interview rounds do these questions come from?

The reported OpenAI questions on this page are filed under 3 rounds: Online Assessment, Phone Screen and Onsite. Filtering by a round gives you the questions candidates were asked at that stage rather than the whole bank at once.

How hard are OpenAI's interview questions?

Of the 87 rated OpenAI questions on this page, the spread is 6 easy, 47 medium and 34 hard. Difficulty is the rating on the question itself, not a prediction of how a particular loop will go.

Where do these OpenAI interview questions come from?

From candidates who sat the interview. Some post the whole loop on the public interview experiences board; the rest are reports we verify and file by company, format and round. Nothing covered by an NDA is accepted, and the sourcing rules are published in full at /methodology.

Has anyone written up their OpenAI interview?

Yes — 116 candidates have published an account of a OpenAI loop, covering the rounds they sat, what they were asked and how it ended. Each write-up has its own page and links to the questions it mentions.

Is there a guide to the OpenAI interview process?

There are 10 guides filed under OpenAI on this page, written round by round: what each stage covers, what it is assessing, and what to practise before it.

Do I need an account to practise OpenAI questions?

Browsing this page needs no account, and 11 of the 87 OpenAI questions listed here open in full for free. The rest are part of a paid plan, and every row says which it is before you click it.
