What this topic covers
The behavioral round checks how you work with people and handle mess: conflict, ambiguity, failure, ownership. It often sets your level as much as the technical rounds do. The reliable prep is a small bank of 3–5 real projects told in a fixed shape (situation, task, your actions, the result, what you learned) and mapped ahead of time to the themes interviewers probe. For AI engineers the best stories come from shipped LLM work: a launch that regressed, an eval that changed a decision, pushing back on a model choice, cutting cost or latency. Expect the openers "tell me about yourself", "your most impactful project" and "a conflict you resolved", then follow-ups that dig into what you personally did. Frontier labs add a values round on how you think about AI safety and responsible deployment.
You’re ready when you can
What interviewers check, from the resources below.
- Pick 3–5 projects and write each as a STAR outline with a measurable result and one reflection
- Map every story to at least two themes (conflict, ambiguity, failure, leadership, learning)
- Say your answers to the Big Three questions aloud in under two minutes each
- Check each story says “I” for the actions you personally took, not “we”
- Explain the Decode → Select → Deliver loop for a single question
- Name the three lenses interviewers assess you through
- State why plain STAR can fall short and what the CARL variant adds
- Correct two of the common misconceptions in your own words
- Build a grid mapping your stories to principles and find the gaps
- Write one new story for “Have Backbone; Disagree and Commit” from AI work (e.g. pushing back on a model or eval choice)
