LLM-Based Binary Classifier Design

Problem Overview

You are given a helper function that accepts a batch of text inputs and returns the token log-probabilities for each input. Using this function, design a binary classifier. The task has several sub-parts: (1) Write a system prompt that conditions the LLM to produce output useful for classification; (2) Compute…

• 3 candidate-reported follow-ups — the exact probes interviewers asked, with the trigger for each
• The rest of the problem statement — full requirements, constraints, and edge cases
• Approach and trade-offs — what passing candidates did, and the mistakes that sink people
