Cengage interview questions

I sent in a letter, my resume, and a link to my writing portfolio. The HR contact was super polite and emailed for times/dates when I could interview. When I sent her my availability, she responded that the manager wanted me two take a couple of writing tests. Nowhere in the job posting did it mention anything about writing tests. I wouldn’t have applied if it did; as a freelancer, I avoid these types of situations since I’ve been burned in the past — working hard on a sample project just to be ghosted after turning it in. And the same thing happened here: I completed the two “tests” (they were very simple - copy edit/suggest ways to make an email and a flyer better), and then I never heard from the HR contact again.
