GridBeyond interview questions

Quite unprofessional and perplexing overall. I was directly approached by their HR on LinkedIn asking if I'd be interested in applying for this position. I confirmed yes and was ok with the required salary range. After I sent my resume, I was asked to create a blog article, three marketing emails, and a mini marketing plan to execute/deliver the above marketing content, The timeline to finish all these was 2 weeks. I found it a bit uncomfortable to spend so much time and effort on these deliverables, while I'm still employed full-time, especially without having spoken to anyone live. But I completed the assignments anyway in good faith, as the assignment instructions indicated that the next step will be an interview. However, no words after I submitted the assignments and when I followed up, I was told they would not be moving forward because my background lacked specific experience in battery management and optimization. This feedback, which was clearly reflected in my resume, came only after I had completed the extensive written assignment without even an opportunity to meet the hiring manager, or anyone over there. I don't know why they didn't identify the lack of specific product category experience when they reviewed my resume if that was a requirement, before approaching me and before requesting the extensive assignment. In my experience, companies typically ask candidates to present or submit assignments (if any) during the interview process. Some may request written responses to behavioral or work background related questions before interviews, which is understandable, but not the creation of a marketing plan and a set of pretty extensive marketing content without a chance to even speaking to someone live. This process seemed to be a disrespectful misuse of candidates' time and gave the impression of soliciting work without proper compensation.
