In two steps, one general talk with hiring manager and hr then solve a problem at home in one week then share them with other group member. One week after second row i got refusal with feedback.

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.
