Recruiter screen
30 minutes. Background, level calibration, team interest (research engineering vs product engineering vs infra). Introduction to the take-home project.
Take-home project
4-8 hours. A realistic engineering task - often involves building a small system, extending an existing codebase, or writing a technical analysis. Submitted before the onsite and reviewed by your interviewers beforehand.
Free rep: Coding challenges with a real sandbox →Take-home review (technical)
60 minutes. Deep dive on your submitted project. Interviewers have read your code and will probe decisions: why this approach, what are the failure modes, how would you extend it. This is the round where shallow work is exposed.
Free rep: Coding challenges with a real sandbox →Onsite: Applied coding
60 minutes. Practical problems - API design, data pipeline logic, evaluation tooling, debugging. Less algorithmic puzzle, more 'here's a real problem we encounter, solve it.' Python is standard.
Free rep: Coding challenges with a real sandbox →Onsite: System design
60 minutes. ML-infrastructure flavored: model serving architecture, prompt management systems, evaluation pipelines, rate-limited inference APIs. Anthropic thinks in distributed systems AND ML systems simultaneously.
Free rep: Design walkthrough: Design a Distributed Cache (Memcached / Redis Cluster) →Onsite: Values and mission
45-60 minutes. Not a soft round. Anthropic screens for authentic engagement with AI safety and alignment. Expect questions about how you think about model behavior, capability vs safety tradeoffs, and your personal motivation for working on these problems.
