Prompt engineering is the skill of asking AI clearly to get reliable, useful results. The same model gives wildly different answers depending on the prompt.

Role & context

Set the scene.

Tell the model who it is ('You are a senior analyst') and give the relevant background. Context steers the whole response.

Techniques that work

  • Role & context — tell the model who it is and give the relevant background.
  • Clear, specific instructions — say exactly what you want and any constraints.
  • Few-shot examples — show one or two examples of the desired output.
  • Chain-of-thought — ask it to reason step by step for complex tasks.
  • Output format — specify the structure (JSON, bullet list, table).
  • Iterate — refine the prompt based on the result.

Good prompting turns a generic tool into a precise one, and underpins assistants, RAG and agents.

Why employers ask about this

Prompt engineering is a practical, in-demand skill that multiplies the value of any AI tool.

Technical questions
How would you improve an unreliable AI prompt?+

Add role/context, be specific, give examples, specify output format, and iterate based on results.

Behavioural questions
Tell me about getting better results from a tool through experimentation.+

Show iterating methodically toward a reliable outcome.

Real-world scenarios
“An AI keeps giving inconsistent, unusable output.”+

Expected answer: Engineer the prompt — add context and examples, specify the exact format, and iterate until it's reliable.
