The interview consisted of a conversation with the hiring manager, which went well. I was then asked to complete an extensive work task (write 3-4 pages of a children's book and evaluate a 30-minute tv show). I spent a lot of time on these tasks and didn't hear anything for over a week after I submitted them. I emailed the hiring manager, who told me that they would get back to me in a couple of weeks. They have since ghosted. I have not heard from them at all. I have no problem completing work tasks as a part of the interview process, but ghosting a candidate after them is unprofessional and disrespectful.
