 The most challenging part of building a product portfolio is really prioritizing what to include in the product portfolio. Like knowing what's important to include in a product portfolio, because there's just so much to learn as a PM. There are so many skills. There are so many key core competencies. How do you showcase your skills within constraint? Like within, let's say, like a short in a very concise form to potential hiring manager, because they have short attention span. They don't have time to to learn the entire life story of your career, right? What I found really helpful was, so I joined product manager accelerator by Dr. Naisli, which is, you know, your program. And one of the most useful module for me was when the product portfolio module, because it kind of refreshed my knowledge as a PM on some of the PM foundational thinking and PM foundational skills. And two is like, how do you structure your response for the product stands question, which is the product case question.
