Prompt Engineering Interview Pack - Medium With Hints

Level: Medium How to use: Use the hints to sharpen tradeoff language and scenario framing.

Interview Questions With Hints

Senior Engineer

1. How would you design the prompt for a user asking, "Recommend something like Attack on Titan but with more politics"?

Hint: Use upstream candidate selection, a narrow recommendation-explainer prompt, and concrete similarity dimensions such as tone, pacing, and intrigue.

1. How would you prompt a policy answer differently from a product-attribute answer?

Hint: Policy uses retrieved chunks and completeness handling; product attributes should prefer structured catalog fields and avoid speculation.

1. What prompt changes would you make when the UI expects strict JSON output?

Hint: Explicit schema, exact top-level keys, no markdown fences, empty arrays for missing fields, and parser validation outside the prompt.

Staff Engineer

1. How do you decide what belongs in the system prompt versus retrieved context versus structured business input?

Hint: Put durable rules in the system prompt, factual evidence in retrieved context, and live business facts in structured inputs.

1. How would you keep a long multi-turn conversation inside token budget without losing key preferences?

Hint: Summarize history, preserve explicit preference slots, and reserve output tokens before expanding history.

1. Why can adding more retrieved chunks reduce answer quality instead of improving it?

Hint: Higher recall can lower precision, increase contradiction risk, and dilute prompt focus.

Product Analyst

1. What prompt-level changes would improve concision without making the chatbot feel robotic?

Hint: Set sentence targets, section limits, and priority ordering instead of only saying "be concise."

1. How would you make follow-up suggestions useful instead of generic?

Hint: Tie suggestions to the actual products, policy path, or current unresolved question.

Applied Scientist

1. When would you use zero-shot, one-shot, or few-shot prompting in this project?

Hint: Zero-shot for stable formatting tasks, few-shot only when it fixes a repeatable behavior gap worth the extra tokens.

1. How would you adapt prompts for multilingual use without weakening business constraints?

Hint: Keep rules language-agnostic, answer in the detected language, and preserve official product or policy terms when needed for accuracy.
