My dear friend Swoozy has started out on her writing career, and was preparing to interview someone for a focused piece related to sex education. She asked for my advice, and I wound up writing up a fair amount for someone who wasn't trained in being a journalist, but has good instincts for representing someone else accurately.
I just kept adding to this and structuring it, and thought it was worth sharing, as I couldn't find anything that was quite as focused on how to interview people for a written article (print or online). Most of the advice is a basis for podcasting and in-person interviews, too. I've now published it at Medium, where you can chip in with comments or advice.
