can you talk about your experience and how it fits into this role?
11:25
Absolutely, I'd love to share that! So, I've been in the product design space for over six years now, and I've had the chance to work on a variety of projects that really align with what your company is all about. Currently, I'm a Senior Product Designer at Acme Corp, where I lead the design strategy for the growth team. One of the key things I focus on is understanding user needs through both qualitative and quantitative research.
