As a Product Owner who conducted a painful amount of interviews last month, the solution is to talk to and observe your users.

I'd highly recommend the Product Bakery podcast as set of great resources for learning more about how to develop great user interview/research skills, whether you work in Product or in design/development more directly.

I discovered the podcast after landing on Christian Strunk's blog (one of the hosts) and it's greatly improved my Product skills and mindset.
