Meta interview questions
240 coding problems in the Placed library have been reported in Meta software engineering interviews, along with 15 behavioral questions. Every one can be run as a timed mock interview with a voice interviewer and a scored report.

Meta runs an AI-assisted coding round
In that round you work with an AI assistant and are graded on how you direct it and check what it gives you. Placed has a track for it.

- Ownership & Initiative
Describe a project where you were the person who made things happen, not just the person assigned to it. What specifically would not have shipped without you? What did you do that nobody asked you to do?
- Ownership & Initiative
Describe a time you shipped something end-to-end — design, build, release, and follow-through — on a short timeline. What trade-offs did you make to hit the deadline? What would you have done differently with more time, and what would you have kept the same?
- Dealing with Ambiguity
Tell me about a time you had to make a significant technical decision with incomplete information and real pressure to move forward. What did you do to reduce the uncertainty before committing? How did the decision turn out, and what would you do differently?
- Dealing with Ambiguity
Describe a project where the requirements kept shifting. How did you stay effective without losing time to churn? How did you communicate progress when the target was moving?
- Dealing with Ambiguity
Describe a time you had to choose between two architectural approaches with real trade-offs and no clear winner. How did you make the call? How did you communicate the reasoning so the team understood why it wasn't arbitrary?
- Collaboration & Influence
Tell me about a time you had to get a team to adopt a technical decision you believed in, without having authority over them. What made it land — the evidence, the framing, the trust, something else? What didn't work?
- Collaboration & Influence
Tell me about a time you worked closely with a PM, designer, or data scientist whose approach to the problem was very different from yours. How did you calibrate to each other? What came out of that collaboration that neither of you would have produced alone?
- Conflict & Disagreement
Tell me about a time you disagreed with your manager on something important. How did you raise it? What happened, and how did it affect the working relationship going forward?
Practice a behavioral round and the interviewer asks follow-ups on your answers.
