Interview with the content lead, then with HR. They asked about my past experiences and talked to me about how the ability to work in fast-paced environments would be important here

After four rounds and two months, they ghosted me. I first applied on Indeed. The person who would be my direct manager reached out and asked for different writing samples than the ones I had provided. I sent them to her and she scheduled an interview with me. During the interview she asked more questions about what I know rather than what I can do. I was asked to define terms and explain sentence structures. After the interview she sent me the next steps, which included a 1200 blog post in 48 hours. I completed the task and she said she would like me to meet with her again; and this time we would be joined by the CEO of the company. At this point, I'm getting excited about a possible job offer. During the interview, she told me my writing sample was an 8 out of 10 and assured me that was a high score. The CEO then proceeded to ask me many of the same questions I had in my previous interview. They then started to ask me random questions like "do you travel a lot?" and "tell me something going on in the news." At one point he also said "you work in Finance? What's a stock?" The whole thing felt very rude and patronizing, especially considering all the time and work I had put in already. They often muted themselves and talked between themselves as I was answering questions. They then asked for more writing samples. I sent them and they said they would be in touch. I never heard from them again. I can't help but wonder if the work I did was used as free labour or if they just moved on to someone else. Overall, terrible experience and a huge waste of time.
