Zilliant interview questions

Met with recruiter for the initial conversation then moved onto discussion with hiring manager and then presentation to hiring manager and other stakeholders, I believe there was 1 final interview after with VP of Marketing. After spending significant time preparing a detailed project presentation, I was told that initial feedback was very positive. However, I never heard back from the recruiter despite follow-ups. It was disappointing to invest so much effort and receive no closure or communication afterward.
