Last updated

A software engineer behavioral round covering a 0-to-1 project you built, a time you received negative feedback, how you deliver critical feedback to others, how you define success for a project or product, and why you want to join OpenAI. It tests ownership, self-awareness, communication and motivation.

In a behavioral round of a software engineer onsite loop, the interviewer asks a set of standard behavioral questions. Each one expects either a concrete story from your own experience or a clear point of view backed by an example:

  1. A 0-to-1 experience: something you built from nothing.
  2. A time you received negative feedback.
  3. How you give negative feedback to someone else.
  4. How you define the success of a project or a product.
  5. Why you want to join OpenAI.

Prepare an answer for each part. Expect the interviewer to probe for specifics: what you personally did, what changed as a result, and what you would do differently.

Clarifying Questions

  • Should the stories come from my current role, or can they come from any point in my career?
  • For the 0-to-1 question, does a new feature inside an existing product count, or should it be a new product, service or system?
  • For the question on defining success, should I answer in general terms or anchor the answer on a specific project I led?

Part 1 — A 0-to-1 experience

"Tell me about something you built from zero to one: a product, service, tool or system that did not exist before you started."

What This Part Should Cover

  • Why the thing needed to exist, and how you validated that need.
  • Your personal role, and the scoping and technical decisions you made under uncertainty.
  • A measurable or observable outcome, and what you learned.

Part 2 — Negative feedback you received

"Tell me about a time you received negative feedback. What was it, how did you respond, and what changed afterward?"

What This Part Should Cover

  • A specific, non-trivial piece of feedback and its context.
  • Your reaction, how you checked whether the feedback was fair, and the concrete change you made.
  • Evidence that the change lasted.

Part 3 — Giving negative feedback

"How do you give negative feedback to someone? Walk me through a time you did it."

What This Part Should Cover

  • Preparation, timing and setting.
  • Specific, behavior-focused content tied to impact rather than to personality.
  • Follow-through, the outcome, and the state of the working relationship afterward.

Part 4 — Defining success

"How do you define the success of a project or a product?"

What This Part Should Cover

  • Outcome metrics versus delivery metrics, plus guardrails that must not regress.
  • Agreeing on success criteria before the work starts.
  • A real example judged against those criteria.

Part 5 — Why OpenAI

"Why do you want to work at OpenAI?"

What This Part Should Cover

  • Motivation grounded in specific, publicly known work of the company that you have used or followed.
  • How your skills and past work fit the role.
  • Why this move makes sense at this point in your career.

Hints

Hint 1

Show the decisions: The interesting part of a 0-to-1 story is what happened before anything existed: how the problem was chosen, what was cut from the first version, and how you found out it worked.

Hint 2

Pick real criticism: Choose feedback that stung and was at least partly right, and make the change in your behavior visible in a later situation.

Hint 3

Answer with a case: Anchor your approach in one real conversation: what you observed, how you raised it, and what the other person did next.

Hint 4

Separate outcomes from outputs: Distinguish shipping on time from the change the work was meant to cause for users or the business, and say when and how each is measured.

Hint 5

Make it two-sided: Connect something specific about the company's work to something specific you would bring, instead of praising the company in general terms.

Follow-up questions

  • In your 0-to-1 project, what did you decide not to build, and how did you know that was the right call?
  • Tell me about a time negative feedback you gave was not received well. What did you do next?
  • Describe a project that met its success metric but that you still consider a failure, or the reverse.
  • What would you want to work on first if you joined, and why?
