Blissy interview questions

After a first interview (very informal conversation, talking about e-commerce trends, new Amazon tools, best practices, etc.) that went longer than expected (always a good sign), I was asked to provide a document answering a list of questions, and offering suggestions and points of view on what they were currently doing. After I provided such the document, I was ghosted by the company. I feel that the process was just an excuse to get a free consulting session.
