How to prepare for a product manager interview

Product manager interviews test how you balance user and business needs, set priorities and work with stakeholders. You may get a product case, a priorities exercise and a presentation. Prepare true stories about decisions you made, requests you said no to and how you measured results. Use the employer's product before the interview.

What a product manager does

The UK government's role framework says a product manager makes sure products provide value. They do it by balancing user needs and business needs. In the role, you:

  • work with teams of different specialists to frame the problem
  • bring together the team's views, user needs and business needs
  • make decisions on priorities for your teams
  • make sure teams meet the right standards

At the product manager level, the framework says you lead a product from discovery through delivery and improvement to retirement. You also set priorities and measure outcomes.

The national job profiles we checked in the US and UK don't have a product manager profile. New Zealand's careers service lists product manager as another name for a product development manager. So read each job ad closely for what the role involves.

Skills employers look for

The UK framework lists the skills for a product manager. Each one is something an interview can test:

  • Using user insights. Speak for users in discussions, and use their needs to set priorities.
  • Value for money. Estimate the value of each item on your roadmap, and compare effort to value.
  • Product outcomes. Agree measures of success with others, and use trusted data to decide.
  • Stakeholders. Understand them, communicate clearly and resolve issues.
  • Strategy. Work with users and stakeholders on a vision, and review it often.
  • Agile and Lean practices. Choose the right way of working, and adapt when something doesn't work.

The interviews you may face

Each employer runs its own process. You may face some of these:

  • A screening call about your experience. See our phone screen guide.
  • A product case, such as how you would improve an app or service you use.
  • A priorities exercise, where you rank a list of requests and explain why.
  • A presentation. The UK Civil Service, for example, says you may be asked to give a presentation and answer questions on it.
  • A stakeholder scenario, such as a senior leader asking for a feature users don't need.
  • A behavioural interview about past products. Read our guide to behavioural answers.

Questions that test each skill

These are themes, with sample wording. Real questions vary by employer.

  • User needs: "How do you find out what users need before you build?"
  • Priorities: "You have ten requests and room for three. How do you choose?"
  • Outcomes: "How would you know if a new feature was working?"
  • Stakeholders: "A senior leader wants a feature your research doesn't support. What do you do?"
  • Saying no: "Tell me about a time you turned down a request."
  • Strategy: "Where would you take our product in the next year?"

Answer "tell me about a time" questions with STAR: the situation, your task, the actions you took and the result.

What to prepare

  1. Use the employer's product if you can. Note three things you'd improve, and why.
  2. Pick two products or features you worked on: the problem, the users, your decisions and the result.
  3. Know the measures you used, such as sign-ups, completion rates or time saved.
  4. Prepare STAR stories about a hard priority call, a failed idea and a stakeholder you won over.
  5. Practise a product case out loud: users, problem, options, choice, measure.

Be exact about your role. If you supported a product manager, say so.

An example answer about saying no

Here is a made-up answer for a made-up person. Use it to see the shape of a strong answer, then tell your own true story.

Made-up example

Ines, a product manager for a city's parking permit service

Question

“Tell me about a time you said no to a feature request.”

Situation

I led the product team for a city's online parking permits. A senior manager asked us to add a chat feature.

Task

I had to decide if it was worth building, with a team of five and a full roadmap.

Action

  • I looked at our support data and found 60% of contacts were about one confusing renewal step.
  • I ran five short sessions with users, and most struggled at that same step.
  • I estimated chat at eight weeks of work and the renewal fix at two.
  • I showed the manager the data and proposed fixing renewals first, then reviewing chat.
  • I agreed a measure with her: support contacts about renewals each month.

Result

After the fix, renewal contacts fell from about 600 a month to 150. The manager agreed chat wasn't needed for now.

Ines says no with evidence and offers a better option. She agrees a measure first, so the result is clear.

Questions

Do I need a technical background to be a product manager?

Not always. The UK framework describes the role through users, value, outcomes and stakeholders, not coding. Some ads do ask for technical knowledge, so check.

What if I've never had the product manager title?

The UK framework says the role can be a first step for people who have worked in other digital roles. Show the product work you did, and be exact about your title.

How do I answer a product case question?

Start with who the users are and what problem they have. Then give options, pick one, and say how you would measure success.
