Clutter Operations interview questions

Before any interview or conversation, they emailed me an assessment assignment and asked me to provide a detailed response and example emails. I was very thorough and have more experience than the position called for, but I didn't hear anything for weeks, even after I followed up. Eventually they emailed that they weren't moving me forward, but didn't provide any feedback. I think they're just gathering information and not necessarily interested in the candidates they're contacting. Seems like other candidates for various positions have had similar experiences.
