Phone screen, Hiring manager interview, Take home assignment, Interview with Engineering team discussing assignment, and a Final Interview with department manager. The final interview was more of an informal discussion/organizational fit. Assignment was broad, goal was to create a microservice that allowed a user to interact in different ways with an LLM. There were several suggested directions and ideas for testing beyond just writing up an API (testing scalability, handling different traffic scenarios, etc). There was no strict time limit, but they said people typically spend 8hrs or so.
