How does a strong candidate differentiate themselves in an interview?

The biggest trait for me is genuinely caring about the audience and being curious about their needs. I can teach someone how to do competitive analysis or script a product demo, but I can't teach you to care about the people behind the screen.

I also get very excited when I see people who can connect the dots across multiple teams and skill sets. PMMs act as the bridge between the audience and the organization, so they need to be able to translate pain-points into product improvements in their conversations with Product Managers, insights about how the customer speaks into campaign briefs for creative/demand-gen/performance marketing teams, etc.

Strong candidates can tell the full story from finding and articulating an insight, linking that insight to a next action (update onboarding, make a demo, etc.), taking or facilitating the action, and then measuring the outcome. It's not enough to just say that you ran a product launch or updated a product tour. WHY did take those actions? How did you measure them? Do you consider it to be a success? If not, what would you change next time to be more successful?
