In what careers or industries are these certifications useful to have? When have you found this additional knowledge to be helpful?
I am starting a digital marketing internship soon and because my primary area of study is graphic design and I don't really know much about marketing, I want to get caught up to speed as much as possible before my position starts.
Are these free certification courses worth my time? Will they actually come in handy if I was to eventually go into a career in graphic design or even start my own business some day?
