Values and mission

A conversation about the mission, judgment, and how you work with people

What they actually ask

The question shapes this round uses. Larpy does not read these out. It builds each one from your own resume, because the generic version is the one you have already rehearsed.

“Why Anthropic, and what draws you to this work specifically?”
“Walk me through a real disagreement with a teammate and how you handled it.”
“How do you make a decision when the situation is genuinely ambiguous?”
“Reason out loud through a tradeoff in your own work that you find genuinely hard.”
“How do you take responsibility for safety and quality in what you ship?”

What this round is judged on

Mission alignment · genuine rather than performed interest in the work
Reasoning under ambiguity · thinking through a hard tradeoff live
High-trust, low-ego · kind and direct communication, per the published principle
Judgment · honesty about uncertainty over a rehearsed answer

What happens in each stage›

Recruiter screen: A spoken call on your background and what motivates you. Anthropic says its interviews cover your experience and your motivations, and that time is set aside for your questions. It does not publish a duration.
Technical screen: A live technical interview for most roles, run over Google Meet on Colab or CodeSignal, with reference materials allowed. Some teams use a take-home instead: Anthropic has published one that runs two hours and, unusually, expressly allows AI tools.
Onsite loop: Further rounds on coding, on work you have done, and on motivation. Anthropic does not publish how many rounds there are, in what order, or over how many days, and candidate accounts disagree, so treat the shape of this stage as unsettled.
Decision and team match: Final decision and matching to a team. Anthropic does not publish how this step works.

Built from what Anthropic publishes about its own process and from real interview data. No leaked question lists. The questions you get are generated against your own resume, so they are not from anyone else's interview.

Seven guiding principles used as the values rubric; capability over credentials ("We care about what you can do, not where you learned to do it"); engineers do research and researchers do engineering; all interviews over Google Meet; live coding on Colab and CodeSignal with reference materials allowed and basic syntax expected; interviews are explicitly two-way

The current candidate AI policy, last updated 2025-07-10: Claude encouraged to refine a draft you wrote yourself and to prepare for interviews ("research Anthropic, practice your answers, and prepare questions for us"), not allowed in live interviews, and not allowed on take-homes unless Anthropic indicates otherwise
