Welcome to your interview.
The question is on your right: STaR vs PLANSEARCH for Coding. 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 comparing two ways to improve language model reasoning on difficult software engineering tasks. One approach teaches the model from successful self-generated rationales, while the other searches over candidate plans before attempting a final solution.
Explain the conceptual differences between STaR (Self-Taught Reasoner) and PLANSEARCH when applied to complex software engineering tasks.
