Jobs To Be Done interview questions that get real answers

13 August 2026 · Mariia Tararova

Everyone I showed my first product idea to said they would use it. Not one of them did.

That is not a story about bad luck. It is a story about bad questions. I was asking people to predict their own future behaviour, which nobody can do well, and they were being kind to me, which most people are.

Jobs To Be Done fixes this by changing the subject. You stop asking about your product. You ask about the last time the problem actually happened to them.

Why "would you use this?" tells you nothing

Three things go wrong at the same moment when you ask someone to imagine using your app.

They want to be nice. Saying no to a visibly excited person is uncomfortable, and most people quietly avoid it.

They are guessing. Predicting what you will do in a situation that has not happened yet is genuinely hard, and people are bad at it even when they are trying to be honest.

And they answer as a better version of themselves. The one with more time, tidier habits and no urgent thing on fire.

You cannot fix this by asking more carefully. You fix it by asking about the past. The past already happened, and it leaves evidence you can check.

The questions

These are the ones I keep coming back to. Not a script to read out loud, more a set of places to push when the conversation gets vague.

How to tell a good answer from a polite one

A good answer is boring and specific. It has a Tuesday in it. It names a tool, a person, a number. It often wanders somewhere you did not plan to go, which is usually the useful part.

A polite answer is smooth and general. It uses the words you used. It sounds like a positive review of a product that does not exist yet.

If someone repeats your own pitch back at you in slightly different words, you have not learned anything. You have been agreed with, which feels similar and is not the same.

When that happens, go back to the last concrete thing they mentioned and ask about that instead. "You said the file came in wrong. When was that?" Specificity is contagious.

What to do with what you hear

Five interviews is enough to notice a pattern. You are not looking for people who like the idea. You are looking for the same trigger appearing in more than one story, described in words the people used themselves rather than words you supplied.

Write those words down exactly. They are your product copy later, and they are also the test for every feature you are tempted to build. If a feature does not help with the moment people actually described, it is probably there because it was fun to think about.

That last part is where I kept slipping, which is why I ended up building a tool for it.

Appray does this part for you

Appray walks you through the same territory in eight rounds of questions, then puts every feature you are considering on trial against what you actually said. The result is a Build, Kill or Prove verdict for each one, plus interview questions written from your own answers rather than a template.

It runs entirely on your iPhone or iPad. No account, no sign in, nothing leaves your device, and no AI is involved anywhere in it.
