As a content marketer, if the HR asks you which content assets you have previously contributed to, they are likely trying to get a sense of your experience and skills as a content creator. This question is an opportunity for you to provide specific examples of the types of content you have worked on in the past and to demonstrate your expertise in creating various content types.  You can answer in the following way:  “ Some examples of content that I have contributed to before include assets include blog posts, articles, ebooks, whitepapers, infographics, social media posts, videos, podcasts, webinars, and email newsletters. This shows my diverse experience and makes me a strong candidate for the content marketing role.”
