Uber Program Manager, Recruiting interview questions

I applied online initially and heard back within a week from a recruiter that they had filled the position. I received an email a few weeks later from a different recruiter who told me that the position was open again and that she "had heard back from the team and we'd like to move you forward with the interview process." I did an initial phone interview then was asked to complete a case study presentation, which I completed and returned. I never heard back ever again. I emailed the recruiter twice and said if they weren't interested, just let me know and I'd close the book and move on. Not a single word back. The ironic part is that particular recruiter has "passionate about candidate experience" all over her LinkedIn profile. My candidate experience with Uber is the worst I've ever had in my 16 years of professional experience. I now use it as an example when I speak at conferences on how NOT to treat a candidate.
