C3 AI Product Designer interview questions

I applied through their job posting, and was contacted by their recruiter via email to schedule a 60-minute video interview where I will be presenting my portfolio to 2 of the Designers. There was no HR screening call prior to the portfolio review and they didn't provide further instructions on that. There was only one designer showing up during the interview. He was friendly and shared helpful information about the role and the team. He asked questions about my design process and how I worked with the cross-functional team. Overall, it was a great conversation but I didn't hear back from them more than a week after the interview. I guess this means I am rejected for this role.
