I'm looking into becoming a blog writer for businesses and many times, they are looking for specialists in their field. How do I convince potential employers at the application and interview stage to convince them that, although I don't have the knowledge and experience in that specific field, I'm more than willing to dive in learn and immerse myself into this niche, if given the chance. This also goes for potentially starting a freelance writing career where I would need to find new clients. Thank you!
