Example Answer

The way I'd explain it in an interview is this: Common prompt-engineering challenges include ambiguity, prompt brittleness, overlong context, format drift, hallucination, and poor performance across edge cases. A prompt may work well on a demo example and then fail as soon as user phrasing, context quality, or task complexity changes.

I usually address that with tighter specifications, better examples, explicit output schemas, and evaluation against a realistic prompt set instead of cherry-picked cases. I also try to separate instruction, context, and examples clearly so the model has a cleaner task boundary. When prompts get too complicated, that is often a sign the surrounding system should do more work instead of pushing everything into one giant prompt.

Common Poor Answer

A weak answer says the main challenge is finding the right wording, without discussing robustness, evaluation, edge cases, or system design around the prompt.
