Interview question: tell me about a time a customer did not understand something

How to answer "tell me about a time a customer did not understand something"

This question comes up often in interviews for customer service, customer success, claims and health admin roles. It sounds easy. The common mistake is a vague answer like "I always explain things clearly", which is a claim with nothing behind it.

If you are moving from a call centre or customer service seat into one of those roles, this question will come up.

This guide shows you how to give a clear, specific answer.

Why interviewers ask it

The interviewer wants to see three things:

You notice when someone is confused, even when they do not say so.
You change how you explain, rather than saying the same thing louder.
You stay patient and do not make the person feel silly.

This matters most in claims, customer success and NDIS coordination. In those jobs you explain rules, decisions and products to people who are stressed or new to the system.

The shape of a good answer

Use four parts. Many people know this as STAR: situation, task, action, result.

Situation. One or two sentences to set the scene.
Task. What was your job in that moment?
Action. Most of your answer. What did you do, step by step?
Result. What happened at the end?

Aim for about 90 seconds to two minutes out loud. That is roughly 200 to 250 words written down.

A weak answer

"I had a customer who was confused about their bill. I explained it to them and they were happy at the end."

This tells the interviewer nothing. What was the confusion? What did you change? What actually happened?

A strong answer

Here is an example for someone from a contact centre:

"I was taking calls about home insurance. A customer rang because a letter said part of her claim was declined. She was upset and kept saying the letter made no sense.

My job was to help her understand the decision so she could choose what to do next.

First I asked her to tell me what she thought the letter said. That showed me where she was stuck. She did not know her policy had a limit for one type of item. She had never heard the word sub-limit.

So I stopped using policy words. I said her policy had a cap on that type of item, a bit like a phone plan that caps your data. That made sense to her straight away.

Then I took her through her options one at a time and checked after each one that it was clear. At the end she said she still did not like the decision, but she understood it. She thanked me and did not ask to escalate."

This works because it shows you listening first, finding the real problem, changing your words on purpose and checking along the way.

Four things a strong answer includes

1. You listened before you explained. Good answers start with a question, such as "What part is not making sense?" or "Can you tell me what you took from the letter?" It shows you find the gap before you fill it.

2. You changed your approach, not just your words. Maybe you used a comparison. Maybe you went one step at a time, or offered to send it in writing. Name exactly what you did. "I swapped the policy terms for plain words" is much stronger than "I explained it more clearly."

3. You checked they understood. "Does that make sense?" is weak, because people often say yes when they mean no. Try "Just so I know I have explained it well, what will you do next?"

4. You had a real result. It does not need a perfect ending. A customer who still disagreed but understood, and did not escalate, is a real result.

Match the example to the job

The shape stays the same. The example should suit the role you want.

Customer success. Pick a time you helped someone use a product or service they were getting wrong. The confusion is usually about how something works.

Claims. Pick a time you explained a rule or a decision to someone who was upset. Patience under pressure matters here. See getting into claims from customer service.

NDIS coordination or health admin. Pick a time you helped someone who did not know the system at all. Plain words and checking understanding matter most. See the NDIS support coordinator career change guide.

Reception or admin. Pick a time you stayed calm when someone asked the same question several times.

Your example does not have to be a customer. A patient, a colleague or a member of the public works too, as long as the skill is the same.

Mistakes to avoid

Blaming the customer. Even if they were wrong, "they just did not get it" makes you sound impatient. Frame it as a problem you solved together.

A long set-up. If the situation takes more than 30 seconds, cut it. The interviewer wants to hear what you did.

No ending. Many people trail off after the action. Always finish with what happened.

Jargon. "I de-escalated the interaction" sounds empty. Say what you actually did.

Practise it out loud

Reading an answer is not the same as saying it. Write yours in the four parts, then say it out loud three times and time it. Our guide to interview practice at home shows a simple method you can do alone.

If you want feedback, the twelve-week Sprint is A$299. It includes interview practice out loud with AI feedback after every answer and a score, a resume, a cover letter and a LinkedIn line for every real job ad you bring in, and an Australian career coach who reviews a targeted resume or an application up to three times and answers your messages in writing.

Questions that often come with it

"Tell me about a time you dealt with a difficult customer." See how to answer the difficult customer question.
"Give me an example of when you explained a complex process." Use the same four parts.
"How do you check that someone has understood you?" Have a short, specific answer ready.

Frequently asked questions

How do I answer 'tell me about a time a customer did not understand something'?

Use four parts: situation, task, action and result. Keep the set-up short, spend most of the answer on what you did to find the confusion and explain it a new way, and finish with what happened. Aim for about 90 seconds to two minutes out loud.

What if I cannot think of an example?

It does not have to be a formal complaint. A patient, a colleague or a member of the public who was confused about a form, a rule or a product works too. The skill being tested is the same.

Does my example need a perfect ending?

No. A customer who still disagreed with a decision but understood it, and did not escalate, is a strong result. Interviewers care more about how you worked than about a happy ending.

How do I show patience without sounding scripted?

Describe what you did, not how you felt. 'I let her finish before I said anything, then asked what part of the letter she was stuck on' shows patience. 'I showed empathy' does not.
