Summary

Point72 ML Engineer interview with a prompt engineering question that was more open-ended than I expected. The whole thing felt less like a coding screen and more like a product-adjacent design exercise, which threw me a bit.

Questions Asked (1)

Q1

You are coaching an Olympic champion. The athlete receives a high volume of news articles daily. Design a prompt for a large language model that filters incoming articles, showing only relevant and actionable content to the athlete and coaching team. The prompt should define the model's role, specify what to include and exclude, require structured output (decision, relevance score, category, summary, reason), and include safeguards against speculation and sensationalism. Assume each article has a headline, source, date, and body text.

Suggested Approach

Start by clarifying the goal: to reduce noise and surface only actionable, relevant articles for the athlete and coaching team. Then structure the prompt with clear role, inclusion/exclusion criteria, output format, and safeguards against speculation. Emphasize the importance of precision over recall to avoid missing critical information.

Pro tip: Frame the prompt as a decision-support tool, not a replacement for human judgment. Mention that you would include a confidence score and a feedback loop to refine the filter over time.

1. Define the Model's Role and Objective

Specify that the model acts as a media analyst for an Olympic champion, tasked with filtering news to support performance and well-being. Emphasize that the goal is to identify actionable insights, not to summarize all news.

2. Set Inclusion and Exclusion Criteria

List what to include (e.g., training tips, competition updates, health and recovery, mental performance, logistics) and exclude (e.g., gossip, unverified rumors, negative speculation, distractions).

3. Specify Structured Output Format

Require a JSON output with fields: decision (e.g., 'include' or 'exclude'), relevance_score (0-1), category (e.g., 'training', 'health'), summary (concise), and reason (brief justification).

4. Incorporate Safeguards Against Speculation and Sensationalism

Instruct the model to avoid speculation, rely only on facts from the article, and flag any sensational language. Require it to state 'insufficient information' if the article lacks credible details.

5. Provide the Article and Request Analysis

Include the article's headline, source, date, and body text in the prompt, and ask the model to apply the criteria and return the structured output.

Key Points to Mention

  • Role definition: media analyst for Olympic champion, focusing on actionable insights.
  • Inclusion criteria: training, health, competition, mental performance, logistics.
  • Exclusion criteria: gossip, rumors, negative speculation, distractions.
  • Structured output: decision, relevance_score, category, summary, reason.
  • Safeguards: no speculation, fact-based, flag sensationalism, state insufficient information.
  • Precision over recall: better to miss some relevant articles than include noise.
