Tell me about a time a project you invested in heavily was cancelled. How did you handle it?

How to answer this behavioral interview question: a complete STAR example, the mistakes interviewers watch for, and the follow-ups you should expect.

A strong STAR example answer

I spent five months leading a team of six as the product manager for a partner-integration platform. We had completed the technical design, built roughly 40 percent of the roadmap, and I had personally championed the project through two rounds of funding review. Then a strategy shift followed a major acquisition, and leadership cancelled it with two weeks' notice.

Honestly, it stung — I had tied a lot of professional identity to that roadmap. My first responsibility, though, was the team. Within 48 hours I held one-on-ones with each member to talk through what the cancellation meant for them, and I worked with engineering leadership to place everyone on priority teams within three weeks.

Then I ran a structured retrospective. Instead of treating the work as waste, I documented which components were reusable. Our authentication module and API gateway design were later adopted by two other teams, saving an estimated eight weeks of development. I also wrote a one-page brief on the market assumptions that had changed, so the organization kept the learning rather than just the scar tissue.

Six months later, leadership revived a narrower version of the project using our preserved designs, and three of the original six engineers asked to work on it again.

How to structure your own answer

• Situation: Convey your genuine investment and why the project was cancelled.
• Task: Define your responsibilities to the team and stakeholders at that moment.
• Action: Show how you handled the people, salvaged the work, and captured the learning.
• Result: Share what came of the salvage and what the experience taught you.

Common mistakes to avoid

• Expressing bitterness toward leadership, which reads as poor executive maturity.
• Pretending the cancellation did not affect you — denial kills authenticity.
• Ignoring what happened to your team members, the part PM interviewers care most about.
• Treating the work as pure waste instead of showing what you salvaged or learned.

Follow-up questions to prepare for

Interviewers use follow-ups to verify your story is real. If you use this question in a real interview, expect probes like:

• Did you push back on the cancellation decision? Why or why not?
• How did you keep the team motivated during those final two weeks?
• What early signals would make you hedge your investment in a project today?
