Welcome to your interview.
The question is on your right: Evaluate an LLM System. Take a moment with it first.
Talk your thinking through with me if you like - when you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes). Discussion and graded submissions share your five interviewer interactions, so spend them well.
You are working on an LLM-powered product feature and need a clear way to judge whether the model is good enough to ship and improve over time. The outputs are open-ended, so simple accuracy is not enough.
How do you evaluate the performance of a generative model?
