Lack of genre knowledge may not be a barrier

If freelancers do not have the precise knowledge of a genre of writing, how would freelancers get their work published in that genre? This would be because some publishers are not exacting. It’s possible to get through on one’s own merits rather than what’s usually required by the more exacting publishers. At least, that’s my experience. The editors liked my ideas, my work, and I wrote it well enough for them. I was never employed as a journalist, but I was an external contributor and I had an affinity with the type of publisher they were.
