What is the best example for a problem solving question?

A recent problem where you found the cause yourself and the result can be measured, even roughly.

Can I use an example from college?

Yes. Freshers can use a project, an event they organised or a part time job. The shape of the answer matters more than where it happened.

What if my example did not work out?

That can be a strong answer if you explain what you learned and what you would do differently.

How long should my answer be?

About a minute. Long enough for the four steps, short enough to leave room for a follow-up.

Problem solving interview questions, with answer shapes

Questions by skill · Updated 2026-10-26

Problem solving questions ask how you handled something that went wrong. The interviewer wants to hear how you think: how you found the cause, which options you weighed, what you chose and what happened.

Answer with one real example, in order, and end with the result and what you learned.

Common problem solving questions

Tell me about a difficult problem you solved at work or in your studies.
Describe a time something went wrong and you had to fix it fast.
Tell me about a problem you could not solve. What did you do?
How do you decide which problem to tackle first when there are several?
Describe a time you found a better way to do a task.

A four step answer shape

The problem: one or two sentences on what went wrong and why it mattered.
The cause: how you found out what was really causing it.
The choice: the options you had and why you picked one.
The result: what changed, with a number if you have one, and what you would do again.

An example answer

In my last job at a phone store, customers kept coming back because their new phones would not receive messages. I checked the returns and saw it only happened when the old SIM card was moved across. I asked the manager if we could add a SIM check to our setup steps and wrote a short checklist. Over the next month the returns for that issue went from about ten a week to two.

Notice what makes it strong: a specific problem, how the cause was found, one clear action and a result with a number. It takes under a minute to say.

What makes an answer weak?

Saying you are a natural problem solver without an example.
Describing a team result without saying what you did.
Skipping how you found the cause and jumping to the fix.
Choosing a problem that was small or not really a problem.
