To answer problem solving questions in an AI interview, walk through four steps in order: define the problem in one sentence, name the options you considered, explain why you chose one, and give the result and how you checked it. AI interview tools usually score a transcript against the employer's competencies, so your reasoning has to be said out loud. A good outcome with no visible thinking tends to earn less than you would expect.
What problem solving questions in an AI interview measure
Public descriptions from vendors and employers point at the same thing: how you reason, not only whether things worked out. As of October 2026:
- HireVue says its video assessments measure competencies including problem-solving skills, using situational judgement questions, scenario-based simulations and past behavior questions.
- For its AI Interviewer, HireVue says each response is evaluated against role-specific criteria and every score ties back to evidence from the interview.
- The UK Civil Service Success Profiles behaviours describe "Making effective decisions" as using evidence and carefully considering "alternative options, implications and risks." Its examples include researching further information and explaining clearly how a decision was reached.
That gives you two question types to prepare for. Past-behavior questions ask what you did ("Tell me about a time you solved a difficult problem"). Situational questions ask what you would do ("What would you do if..."). Both are usually scored on the same reasoning steps.
The four-part shape: define, options, choice, result
| Step | What to say | A phrase that makes it visible in a transcript |
|---|---|---|
| 1. Define the problem | The symptom, why it mattered and the cause you found or suspected. | "The real problem turned out to be..." |
| 2. Options considered | Two or three realistic options, briefly. | "I looked at three options..." |
| 3. Why you chose | Your criteria (cost, time, risk, who is affected) and the trade-off you accepted. | "I chose this because..., accepting that..." |
| 4. Result and check | What changed, by roughly how much, and how you confirmed it held. | "Three weeks later I checked and..." |
Spend most of your time on steps 1 to 3. The diagnosis is the step most answers skip, and it is often the clearest proof of problem-solving skill. Signposting phrases like these also help a transcript stay readable; see how to speak in an AI interview.
Rubric table: weak vs strong problem-solving evidence
This is an example rubric we wrote from the frameworks above. Real employer rubrics vary.
| What the rubric looks for | Weak transcript (example) | Strong transcript (example) |
|---|---|---|
| Diagnosis | "Deliveries were late, so I fixed it." | "Almost all the late orders were packed after 2 p.m., so they missed the last pickup." |
| Uses information | "I had a feeling it was the carrier." | "I compared a month of delivery times by day and by packing time." |
| Alternatives | "There was only one thing to do." | "A second pickup, a new carrier, or an earlier cutoff." |
| Judgment | "It seemed like the best idea." | "A second pickup cost more than the late credits, so I chose the earlier cutoff." |
| Result and verification | "Everyone was happy." | "On-time deliveries recovered within three weeks, and a weekly report now flags drift." |
Example answer: a past-behavior problem-solving question
Question: "Tell me about a time you solved a difficult problem." This is an example we wrote to show the shape, not a real candidate's answer.
"As a logistics coordinator, I saw late deliveries to one region double over a month, and store managers there were escalating every week. The easy answer was to blame the carrier, but first I compared delivery times by day and by packing time. Almost all the late orders were packed after 2 p.m., so the real problem was that they missed the carrier's last pickup. I looked at three options: paying for a second pickup, switching carriers, or moving that region's packing cutoff to 1 p.m. A second pickup cost more than the late-delivery credits we were paying, and switching carriers would take months. I chose the earlier cutoff, accepting that some orders would ship a day later, and I told the store managers before the change. Within three weeks, on-time deliveries to that region were back to normal, and I set up a weekly report so we would see the next drift early."
Each step from the table is a separate sentence, the trade-off is named, and the result includes how it was checked. For more examples in technical, business and people settings, see tell me about a time you solved a difficult problem.
Example answer: a situational problem-solving question
Question: "What would you do if a report due this morning showed numbers that didn't match the source system?" Example answer we wrote:
"First I would find out how big the gap is and where it starts, by comparing one day's totals in the report with the source. If it's a known delay, such as data that hasn't refreshed, I'd note it on the report and send it on time. If I can't explain it within about an hour, I'd tell the person waiting for it, give them the parts I trust, and say when the rest will be ready, because a late correct report is better than a wrong one on time. Afterwards I'd add a check that compares the totals automatically. I did something similar last year when a filter change dropped one store from our sales report."
Clarify, weigh options, decide and check, then link to a real past example if you have one. Our guide to situational questions in an AI interview goes deeper on this format.
Before and after: a problem-solving answer rewrite
Before (example): "I'm a really good problem solver. When something breaks I just figure it out. One time our booking system went down and I fixed it pretty quickly and everyone was happy."
After (example): "When our booking page started failing for some customers one Monday, I first checked which ones: only people on older phone browsers. I had two options, roll back that morning's update or patch the form. Rolling back would also remove a fix customers had asked for, so I patched the form and tested it on the two oldest browsers we support. Failed bookings stopped within the hour, and I added those browsers to our release checklist."
The before version claims a skill. The after version shows it: a diagnosis, two options, a reason and a check. Software engineers answering technical problems out loud can use the same shape; see technical questions in an AI voice interview.
Practice routine for problem-solving answers
Take the assessment yourself and follow the employer's rules — use CoPilot Interview to practice beforehand.
- Pick two stories. One where you diagnosed a cause others had missed, and one where you chose between real options under a constraint.
- Write the four steps as bullet notes. If you can't name the options you rejected, add them before you rehearse.
- Answer out loud and get scored. Our free AI interview assistant includes a Mock Interview mode that scores each spoken answer out of 10 with what to fix and a model answer, and the free plan includes 15 minutes every day. With nothing to install, the browser demo has 145 real interview questions across 10 tracks, graded by AI.
- Practice one situational question cold. Answer a "what would you do" question you haven't seen, using clarify, options, decision, check.
- Prepare the follow-ups. "Why not the other option?" and "How did you know it worked?" are the obvious probes; see AI interviewer follow-up questions.
Practice thinking out loud, with a score
CoPilot Interview's Mock Interview reads each question aloud, listens to your spoken answer and scores it out of 10 with what to fix and a model answer. The free plan includes 15 minutes every day, with no card.

What do problem solving questions in an AI interview look for?
Usually your reasoning: how you defined the problem, the information you used, the options you weighed, why you chose one and how you checked the result. Employers choose the competencies, and vendors differ in how they score them.
What is the best structure for a problem-solving answer?
Define the problem, name the options you considered, explain why you chose one, then give the result and how you checked it. It fits inside STAR, with the define, options and choice steps forming most of your Action.
How long should a problem-solving answer be?
About 90 seconds to two minutes for a past example, and a little less for a situational question. Check the time limit in your invitation, because one-way video platforms set their own.
What if my problem-solving story did not work out?
You can still use it if you explain your reasoning, what you learned and what you changed afterwards. Many rubrics credit clear thinking and learning, not only a perfect outcome.
How do I answer a "what would you do" problem-solving question?
Say your first step and why, the options you would weigh, the decision you would make and how you would check it worked. If you have handled something similar, mention it briefly at the end.
How can I practice problem-solving questions for free?
Write two stories as four bullet notes each, then answer out loud and get feedback. CoPilot Interview's free plan includes 15 minutes every day with Mock Interview, and the browser demo at /try needs no install.
