Describe a situation where you identified a market opportunity that others in your organization had missed.

Spotting a pattern nobody owns is what separates a PMM from someone who executes requests. This question tests curiosity, how carefully you size an idea, and how you get a team to act on something it hadn’t planned for.

Interviewers score this one on market expertise. On the rubric, a Strong answer on market expertise understands buyer motivations beyond stated needs.

1. Say where you saw it. Describe the ordinary work that exposed the signal.
2. Check it with numbers. Size the segment before you pitch it.
3. Handle the skeptic. Name who doubted it and what they were worried about.
4. Ask for a small test. Explain the pilot you proposed and what it cost.
5. Report the outcome. Give the result and the moment you had to correct yourself.

Every name and number here is invented. Your version should use your own.

“While reading support tickets for a different project, I noticed that about one in five new accounts came from small agencies using our reporting tool for client work. Nobody was marketing to them. Our website, sales team, and pricing all assumed an in-house buyer. I pulled the numbers before saying anything. Agencies were twenty-two percent of signups and added seats faster than any other segment. I took it to the head of sales, who thought it was a distraction from enterprise. I asked for a small pilot instead of a strategy change. Over three months I built one landing page, asked product for white-label exports, and proposed a partner pricing tier. Agencies grew to fifteen percent of new revenue. My mistake was sizing the segment too optimistically at first. I claimed forty percent, the sales lead caught it, and I lost a few weeks of credibility before the real numbers earned it back.”

“I noticed a new customer segment that we weren’t serving and shared the idea with leadership. They liked it, so we built a plan to target the segment, and it became a significant source of growth.”

The weak answer skips how you found the signal, how you sized it, and who pushed back. Add the data, the skeptic, and the small test you used to earn approval.

• Why hadn’t anyone else noticed it?
• How did you size the segment?
