Constructive Dialogue Institute interview questions

I applied online and moved quickly to a Zoom interview with a recruiter. Afterward, I was asked to complete a comprehensive, 4-part assignment. While I appreciated that the company compensated me for my time ($100 amazon giftcard), the experience soured after the project was submitted. Despite meeting all requirements and delivering a high-quality product, I was denied a final interview. When I reached out politely to request constructive feedback on the assignment and interview, I was ghosted. It is disappointing that an organization with "Constructive" and "Dialogue" in its name fails to practice those very values during the candidate experience.
