CAEL.org Implementation & Client Success Director interview questions

I received a call from a recruiter who set up a video interview with me and two individuals at CAEL. The interview went smoothly, and CAEL asked me to complete some homework as a follow up to the interview. I completed the homework the next day and sent it over. I then never heard from them again. It almost felt like they were mining for ideas on how to solve a business dilemma rather than actually looking for someone to fill the role. I feel like the least they could have done was sent me a follow up email advising they weren't moving forward with me.
