AI tools and prompting interview questions

Questions employers commonly ask about using AI tools at work, with answers that show sound judgement.

1
How do you write a good prompt?

I give the assistant a role, the relevant facts, clear limits such as length and tone, and the exact format I want back. For example, for a support reply I include the customer's issue, our policy and a 120-word limit. If the first answer misses, I give specific feedback rather than starting over.

How do you check that AI output is accurate?

I treat it as a draft and verify every figure, name and claim against a source I can read myself. For formulas or code, I test them on cases where I already know the answer. Anything I cannot confirm, I remove.

3
What information would you never paste into an AI tool?

Customer personal data, passwords or keys, confidential pay or contract details, and internal plans, unless my company has approved a specific tool for that data. When I need help with such material, I replace real details with placeholders like [Customer A]. I also follow the employer's written AI policy.

Tell me about a time AI output was wrong.

A good answer names a real case: for example, an assistant summarised a policy and stated a 30-day refund window when ours was 14 days. Explain how you caught it, such as comparing with the source document, and what you changed afterwards, like always pasting the policy text into the prompt.

5
When should AI not be used?

When the decision carries serious risk for a person, such as medical, legal, financial or hiring decisions, and when there is no way to verify the output. AI can help prepare information, but a qualified person must review and decide. I also avoid it where the company policy does not allow the data involved.

How would you make AI-assisted work consistent across a team?

I would create shared prompt templates for recurring tasks, each with a role, examples and a fixed output format. I would also agree on a review checklist, such as checking facts, tone and privacy before anything goes out. Templates get updated when someone finds a better version.

Practise out loud. Say each answer once as written, then again in your own words with your own number or story.

Have a number ready. "My AI tools and prompting score is at benchmark on a timed test" is a stronger answer than "I am good at it". Take the test and quote the result.
