Rackner interview questions

Applied for an open role, received an email later that day through their scheduling application requesting I choose a time for an "interview." I chose a time, and received a confirmation calendar invite titled "interview." I wanted to clarify if this was an initial interview with the team or just a screening call, so I sent an email requesting clarification. I never received a response. Going into the call a week later I was not sure what to expect. I joined the meeting on time, but the interviewer was almost 5 minutes late, and it turned out to be a only a screening call. We chatted for about 30 minutes. It seemed my background would be a good fit for the position, and I was told I should expect an interview confirmation to speak with the team later that day, or tomorrow. They seemed eager to tell me how great the company was and why I should join. A few days went by, and no word. I followed up and a week later and still no response. I have been working in the industry for over 15 years, and I can say this probably one of the oddest experiences I have had with the recruiting process, especially for a small company.
