Anthropic Software Engineer
interview guide
Prepare for progressive coding, AI-assisted code reviews and design discussions, alongside questions about your engineering experience and approach to AI safety.
What to expect at Anthropic
Anthropic's software engineering interviews can include practical tasks involving files, concurrency and existing code. A design discussion may ask you to examine a proposal or write a document, while project and culture interviews explore decisions you have made and how you work with others.
Some routes begin with a progressive online assessment, while others start with coding or design. Confirm the rounds, language and permitted AI tools for your own process.
Preparing for a design review
Do not prepare only a whiteboard architecture pitch. Candidates have been asked to inspect an existing inference design, identify weaknesses and improve it. Others wrote a design in a shared document.
For inference questions, clarify whether a latency target means time to first token or completion, whether batch size is fixed, and what the stated processing-time assumption represents.
