Welcome to your interview.
The question is on your right: LLM Fine-Tuning Bug Hunt. 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 given a PyTorch training script for an LLM fine-tuning run that is failing to converge or throwing runtime errors. Identify and resolve three hidden bugs in the training loop and data loader.
