Design an LLM API pipeline
Company: Scale AI
Role: Software Engineer
Category: ML System Design
Difficulty: easy
Interview Round: Onsite
You need to build a small application feature that calls a hosted large language model API to solve a user task. In the interview, you are expected to:
1. Show how you would call the LLM API.
2. Explain how you would write the prompt so the model produces useful and structured output.
3. Add validation on top of the model response.
4. Discuss what additional concerns you would address before shipping this feature to production.
Assume the exact business task is not the main focus. The interviewer wants to evaluate your ability to integrate an LLM into an application, validate the output, and think through production readiness.
Quick Answer: This question evaluates a candidate's ability to integrate large language models into applications, encompassing API integration, prompt engineering, response validation, and production-readiness considerations.
